If it crashes with your SA:MP client, show what the crash log says if not that if it's GTA_SA.exe possibly something on your side of the end.

I think there may be too many objects. Do you stream them? If not, try Incognito's Streamer Plugin and if that doesn't work, it should be something with ur client.
