"Invalid Annotation Object" error

I'm using Windows XP Pro (SP3) on a 2.66 GHz, 2 GB RAM computer, and while working in an Adobe Acrobat 9 document, I had just saved the file (CTRL+S) and the document froze and I got a Windows error box that asked if I wanted to send an error report, which I did. When I opened Adobe again, it asked if I wanted to open the last file which didn't save correctly, which I did.

Then when I proceeded to work in the document and tried to highlight a sentence I was going to delete, I got an Adobe Acrobat popup box that said "Invalid Annotation Object. OK" but no matter how many times I clicked on "OK," the box kept popping up and wouldn't go away. I tried saving a copy of the document, but the same box was in it and wouldn't go away. I couldn't even work in the document to extract pages or anything else. Huge problem!

Does anyone know what can I do to resolve this problem? (This happened on a Saturday when Adobe phone support is not accessible.)
Correct answer _Roseo_
I have researched this some...I have found a 99% solution, and will be in further contact with Adobe tomorrow.

The 99% solution...if Adobe crashes while you are working on a document (firstly, pray like anything you have saved it recently...) before working on your document again, open up a random PDF after the crash, then close adobe...so that it has closed normally, without crashing.

Now open your document. 80% of the time your document will not have corrupted if you follow this method. Unfortunately, if it does corrupt, you have to find the corrupt page or pages - easiest way I found was to navigate using the up/down arrows rather than scrolling. You then have to delete these pages, and re-insert clean ones.

You won't be able to reinsert until after all the corrupted ones have been deleted.

This is just my solution so far and not anything Adobe have told me, so if this is a fluke just for me I apologise.......

Good luck! I will be speaking to Adobe AT LENGTH re this tomorrow so fingers crossed....

1/16/09 I have had the exact same problem and tried everything and nothing works. Looks like I will have to get a fresh file and start again. I worked on that file the entire day and lost it all.

Hi...as I said I would update this, I thought I'd better...

I have spoken to Adobe who have asked us to work through their troubleshooting guide to rule out all other errors...

As we have this problem with a couple of users at my workplace we're going to see how this works out and then speak to Adobe again if it doesn't resolve the problem!!

PS - I know it wasn't at me, but we're not using any 3rd party annotation tools...

I have had the same problem. For me, Adobe was closed normally on the last occasion; there is no corruption. I had spent over 3 hours adding my annotation and comments as that was the point of using this program...so I don't really want to revert to the original file as this has now happened four times, on each occasion that I have tried to annotate this.

Distiller...not sure what this is or how it will help?

I have tried emailing my document to another user who only had reader installed; they experience the same problem when trying to read it (I managed to save the document as after I press ok about ten times, the message disappears. It then comes up again when I start to move - scrolling up or down. As it's a ten page document....!!)

I have tried saving copies under new file names etc, etc, etc...

Are there any ideas on how to actually fix this without starting from scratch a fifth time - third time lucky didn't do the trick!!!!

Thanks in advance

I had the same problem, but I believe it was because Adobe didn't close correctly the time before and the file lost some consistency. I had to delete the corrupted pages through the "Document" menu and start them over again. Hope that helps!

How do I figure out which pages are corrupted?  I'd delete them if I could, but my document is almost 300 pages.

Hi @Chantal38004374ixih,

 

Hope you are doing well. Sorry for the trouble, and the delayed response.

 

If you are still looking for a solution, you can try the below steps to identify the pages that have invalid annotation objects on them:
1. Open the PDF > Organize Page > Extract Pages and select "Extract Pages As Separate Files".
2. Set the destination to a 'dedicated' folder that won't contain any other files and click OK.
3. During the extraction, click OK in all the message boxes that appear.
4. After the extraction, look in the destination folder to see which pages are missing -- these will be the pages that have invalid annotation objects.

If you're using Pro. you might try using the Document > Examine Document command to remove your Annotation and Comments.

Examine Document is now called "Remove Hidden Information" in Acrobat X, it's under the Protection tab.

You may want to try to run it thru Distiller.
