Corel wont let me save file export print or save as pdf. I have a license

Hi, hope you can help me

I was working fine on corel and it crashed (as always), when i went to open my file it said it was corrupted. I was able to recover it and open it again, but this time it wont let me save, export, print, save as pdf, copy or paste. I know this problem can be related to having a trial but this is not the case. 

When I go to to Help>About CorelDraw, it shows my license number and everything.

Please help!
