Hi, I've been experiencing crashing whenever mods were installed since I got the game a fair few months ago (Excluding mechjeb, which I successfully installed (Wow, right?)) Recently the problem has gotten worse (In the last month or two) with the game now crashing whenever I revert a launch, load a quicksave, leave the VAB or SPH, or try to revert to either of them (Reverting in general it crashes, including to tracking station and Space Center) I've tried a clean install about three times in the last two days. My most recent crashing issue prevents me from even entering the game, it halts loading around cabinInternals/model005 to model008. All of the items it crashes at are actually in the Squad folder. Here's the most recent error report: Unity Player [version: Unity 4.5.2f1_9abb1b59b47c] KSP.exe caused an Access Violation (0xc0000005) in module KSP.exe at 001b:00f6d554.

I'm running on Windows Vista 32bit, with 4GB of RAM. Any help is really much appreciated! Edit: I managed, just once, to get into the game and into the SPH (wow!) B9 Aerospace (The only mod I have) worked perfectly fine (all be it except for some texture issues, but they're not unusual for me), until I tried to launch the plane, and then the game froze.
