Random library titles crash DE 4.5.1

[samb2253269]

Random library books crash DE 4.5.1 when it auto opens after downloading the file. How can I fix this as I have a book I have been on a 3 month wait list for twice that I want to read. This is on Windows 10

Already tried:

Reinstalling

Running as administrator

Running in Windows 8.1 mode

Deleting all copies of the books and trying the above

Setting DE as default to open the file type

Renaming the My Digital Editions folder

Have the issue only with  the one file? If yes hould contact the library to check the file.

[samb2253269]

No, it is multiple files from two different libraries. Some of which worked fine under the previous version of DE which is why I am here not calling my libraries.

[Nanaky]

All files the same file format?

[samb2253269]

All the files from the library are:
Adobe Content Server Message (.acsm)

It should be the library's fault if some files of the same type open and some don't. Except for the problem I reread books quite a lot and some of the ones I am having trouble with I have read before using the previous version of DE which implies that it is DE 4.5.1 that is the problem.

o.O has you check if work if you download a file a secound?

[samb2253269]

Tried redownloading the files, and changing the name of the My Digital Editions folder so the new download was the only book showing in ADE and it still crashes

[Nanaky]

Has you try it with a other file?

[samb2253269]

How do you mean? The library only offers 1 type of file.

Some .acsm files work on the previous version and 4.5.1.

Some have worked on the previous version of ADE but don't on 4.5.1

Some I have only tried on 4.5.1 and some of those randomly work and others don't.

[Nanaky]

That it the file format. Has you try it only with a other eBook?

[samb2253269]

It can't be the file format because I have downloaded the exact same file with two different versions of ADE and the fie opened on the old version of ADE and not on 4.5.1.

The only variable that has changed is ADE.

[Nanaky]

But you can loan a other eBook or not?

[samb2253269]

I have never tried. I don't buy ebooks I only borrow them from the library

[Nanaky]

Then try if works a other file of the Library.

[samb2253269]

The options are .acsm or the Kindle format.

[Nanaky]

Yes i know but should it try with a other file (Other eBook of the Library).

[samb2253269]

I have tried this with many books from two different libraries.

The only file format that is available and that works on my  Nook is .acsm (please note ADE crashes when the book is being transferred to ADE, it freezes before the Nook is even plugged in.

I have tried multiple different books. Some of the .acsm files work. Some of the .acsm files do not work.

And importantly. This problem only started with 4.5.1.

Some of the files I have downloaded before and they didn't crash ADE.

For example. SevenEves worked on the previous version of ADE and not the current one. That is tested from two different libraries.

Anathem worked on the previous version of ADE and works on the current version of ADE.

This is why I think it is an issue with ADE and would like some advice on how to get this POS software working properly.

If is work with the older verison of Digital Edition install the current version and install the older again:

if exist a update for 4.5.1 you can try again.

[samb2253269]

Wonderful. Absolutely effing wonderful.

Well you have solved the problem with only some books opening by making it so no books open.

New books being downloaded to ADE 3.0.1 get the error: Error! Check activation

Books that were already on the library have the error:

An Error Has Been Detected

Activation Server Error

Code E_Adept_Internal

And I know what you are about to say, because when I try to return a title it says the computer is not authorized.

When I go to the Help tab the top line "authorize computer" is greyed out and if I click the second Computer Authorization line it says:

This Computer is already authorized

And then shows my Adobe account information.

Any more ideas?

Thank you for the heko

Anyone else with 4.5.1 issues just dump the POS and put 3.0.1 back and do the above to fix the registry and then redownload all your books

You are welcome.
