Do I understand correctly that you had a crash, and you get all of these messages when trying to reopen ID? Or does this only happen when you try to open a particular file? If only when trying to open that file, are you opening ID first and using the File menu, or are you double clicking a file in Explorer or Bridge?
At the very least it looks to me like you had a crash and the recovery data for an open file is corrupt. I would try moving the InDesign Recovery folder out of your user profile, or rename it, or just delete everything in it, then try to launch ID normally. If you still get the first two errors, try a System Restore to a point before you started having trouble, but if that also does not work it means the plugin is damaged and you should reinstall.
Finally the world is back on its track:
ID launched and allowed creating a new file
ID opened the earlier file without a crash, files opened with its typical messages of colorspace mismatch, font missing, links not having files... sometimes these messages feel good
Re-installation has got things back. I had some doubts about these, but all works:
- System was not restared at all during the uninstall and reinstall, magically it also kept track of serial number (so glad I did not have to hunt that out from records!)
- No earlier windows restore point was required
I am glad all is OK now, but "what" was the problem? And what made it to occur? Any ways to prevent such thing to happen again?
