[Solved] Assertion failed

Whenever I try to start the editor, I get this error. I was told i needed to update my video card, because my old one had only 1GB of ram, so I updated to a GTX 650 Ti Boost which has 2GB ram. I’m still getting the same issue though. Could any one help me out?.. Below I’ve pasted the crash results. (I’ve not pasted them on a site like pastebin, just to make sure I’m not violating the NDA)

EDIT: On a side note, my video drivers crash every time. I did a fresh install on them when I got the new card, Not sure if that might have something to do with it.

Any help resolving this issue would be awesome.

A few days ago, I had updated my drivers trying to get the engine to work on my 550 TI. It turns out it was the card. When I got the new card, I completely forgot to update to the latest drivers. I’ve done so now, and it’s all running smoothly. The issue was outdated drivers.
