I am using Nvivo 10 on a Macbook Pro mid-2010 model using Parallels for Mac. I have been using it successfully for sometime now. However, today when I open ANY of the older versions (created using "Save as copy"), it says "The project "PATH".nvp" could not be opened, due to an unexpected error". I am really devastated by this, because even the backups are not opening. Any of the 4 backups I open also gives the same message.
This happened after I terminated the software, when it crashed on a word document import. After I terminated the application and reopened, this error started. I have already tried logging off Windows as well as restarting. I also tried restarting Parallels as well as restarting the Mac and the error persists. I also scanned the HDD for any errors and none were seen.
I am attaching the screenshot of the error. I would really appreciate if somebody could help me out!
