print errors/crashes in microstation

I am having sporadic issues with microstation crashing in general and blocking out certain functions. 

When im trying to save a print:

the print wont save (nothing happens when I hit the save button), or it will click save but the print will fail.

When im trying to open certain files that open perfectly on someone elses computer:

sometimes the level and reference dialog don't open, or open with blacked out areas similar to the above.

Sometimes clickling the toolbar (File etc.) doesn't do anything.

I've uninstalled and installed SS2,3,4 and the same issues are there.

Any suggestions? Thank you!
