EN X5 start error

Last night, EN X5 worked fine.  This morning I got the following error message on trying to start EN:

“EN X5.0.1 (Bld 5774) has encountered a problem and needs to close”

Expanding the error message:

“Appname: endnote.exe   AppVer: 15.0.15774  ModName: pdfnet.dll  Modver: 5.1.0.0 Offset: 0005bd78”

I have uninstalled and reinstall X5 and its updat (X5.0.1), but EN delivers the same message.

Nothing else was changed on my computer.

Any ideas?

Thanks.

After several uninstall/install attempts, I decided that it couldn’t be the program.  I did some experimenting, at found that one of my librairies had become corrupted.  It took me awhile to figure that out, because I had backed-up the corrupted library last thing yesterday, so copying it back to my main drive didn’t help.  Lost a couple of days work, though.

Thanks!
