Illustrator Crashing on Lauch & Save

Hello, ever since the last illustrator update, Illustrator is giving me a lot of trouble.
When I open the program, it looks like it's going to be fine, but then if I click anywhere to create a new file or open an existing one, it will most likely freeze and become unresponsive. Then, when it sometimes manages to come back, I might be able to work but then if I try to save, unresponsive again. And I lose everything. It's weird because I never-ever have problems with Adobe products. Photoshop, on the same computer, for examples, works just fine.

Things I've tried and obviously didn't work:
- Deleting preferences, through illustrator and manually
- Uninstalling and re-installing many times illustrator (yes with restarts and shutdowns in between)
- Updating the drivers of my computer
- Creating new and trying to modify older files to see if it was a file problem

Please help me, because I don't have any other ideas here...

Thank you
