3 gmod crashes in a row

hey all, I’ve just had 3 crashes (first one was both steam and gmod, other 2 were just gmod). I installed a whole bunch of addons so I guess that’s the reason, but I don’t want to delete all of them so I want to make sure the exact one gets nailed.

I uploaded the 3 crash files: http://www.megaupload.com/?d=RPZB1TUV so if anyone would be so kind (and if you know how to open it, I know little about file extensions) to tell me what the exact problem is, thanks.

Only the G-team (as I think I shall call them) have the correct files to open mdmp. Remove some addons.
