GMod Instantly Closes When Loading Icons

Whenever I try to load new icons, (Note, some icons still load.) the game just instantly closes. This is very annoying, as you can imagine.

Here’s the dump file: http://www.mediafire.com/download/ql31utovo1nbsib/hl2_140122_crash_2014_3_6T18_11_24C0.mdmp

The model you are trying to load is not supported by GMod ( L4D2, Portal 2, Dota 2?, CS:GO, SFM models ) or is corrupter.

Disabled Left 4 Dead 1 & 2 and CS:GO, that fixed it.
Thanks!
