CorelDRAW X6 freezes after the first file save!

When trying to either save the file (a second time) or exit the program, it just freezes. Still can minimize/restore the window, but cant interact with the window in any other way. Save As doesnt work either!

When did the issue start:
- Few days ago, with no clear reason

Possible causes?
- Nothing about the PC has changed, perhaps some windows updates were installed

Are all files affected:
- Yes

Troubleshooting done so far:
- Updated to the last patch available and uninstalled some fonts, since it was suggested that this may be the issue

Workaround:
- I can kill the process after each save and re-open the file, but its very tedious and I frequently forget I was supposed to kill corel

Critical info:
- CANNOT re-install the program (which would probably resolve the issue, since the add-on I need for the Graphtec plotter is very, very, VERY hard to install and make work (last time it took me a month)!
