I need help with the error message below

[jackieb26629005]

I had saved a project and then Captivate did the while not resonding thing.  The next day I got this error:

It wasn't open already, it wasn't sent in an e-mail, It was only worked o using my laptop.  I have tried this with nothing else open.

Any help appreciated, thanks

Sorry to tell you that this is an 'all-round' error message which can be due to multiple reasons. There could indeed be lck files, because the former session was not closed correctly. I never understood the reference to an e-mail unless it meant that cptx is a zipped folder which could have been damaged that way.  

Do you have a backup file? In the most recent releases it is set up automatically in Preferences. If yes, can you open the backup file? 

I hope you don't have a roaming profile, which means that your documents are on a networked drive?

Be careful with clearing the cache because it includes the cache of this project as well which could be a way to recover an older backup.

You can try to clear the Preferences. 

I really hope that the project is not corrupted (damaged).
