Crysis & Rainy Days mod Thread

Greetings all!
First off let me say I'm getting more and more into mods and so I just joined Desura and new here.
I hope I've got this posted in the right section.

A lot of these Crysis mods are fantastic but I'm having troubles with the Rainy days mod. After a few minutes into the mod, I crash with a message, (critical memory loss) I haven't been able to find any solution to this so I hope I can get some help here please.

I'm running an intel i7 2600k
a gigabyte motherboard model P67A-UD3-B3
nvidia gtx 460
8 GB ram
PSU 700 watt
playing @ 1680x1050

Thanks, cheers!
