CD x4 stopped saving.

Been running licensed version of x4 since forever. 

All of a sudden it stopped saving / save as /export. Even if I edit a file it will ask to save changes but won't. Sometimes blinks but doesn't save.

Protexis service is running. 

No errors on startup.

No errors in the event viewer relating to Coreldraw.

F8 didn't fix it. Just wiped out my workspace savings. argh.

I also have CD x18. It saves/saves as / exports fine. But I prefer x4

Its driving me f'n crazy.

Anything else I can try or do ?

Thanks.
