Cannot load certain maps

[Acarlmac]

I installed PR about a week ago and I have been able to play most maps perfectly fine but a few maps I have never been able to load. When I try to load Gaza, Iron Ridge, and Wanda Shan my game will crash to desktop when it is almost finished loading or when it finishes loading but I never see a squad deployment button.

What are your system specs? This problem is probably due to the usual not enough RAM or CPU power. These maps you ha r listed are especially taxing on your components with the addition of burning sands, have you tried putting textures to low? This can help reduce the chances of ctd's

It's a laptop I have 4gb of ram and an Intel Core 2 Duo Processor T6500 (2M Cache, 2.10 GHz, 800 MHz FSB)

I turned textures to low and still CTD with those maps
