CTD on new map load

[SHAz_181]

On two of the new maps so far (Wanda Shan, Iron Eagle) I've CTD'd around 75% through map load. I've turned my settings down to rock bottom and increased my virtual memory a buggerload. The new US Army V.s Taliban map (Can't remember its name) worked just fine, and in 0.91 every other map was working as normal too with good FPS. I remember having a similar issue on the release of another new version of PR a while ago, probably 0.85.

Specs:
ATi X1950 Sapphire
Intel Core2Duo E8500
4/3.25 GB RAM

I've reinstalled PR multiple times and am about to redownload the installers (Oh god). I've played rounds of Burning Sands and aforementioned Insurgency map since install but no other maps.

I've CTD'd multiple times around 10-30 minutes into several rounds too. This is frustrating. It all worked fine before the update. Both on Silent Eagle and Lashkar Valley.
