Game crashing - Updated to 1.3.1 then reverted to 1.3.0

[Berkyjay]

Hi everyone, I'm having issues with KSP crashing on me.  It was working fine last evening but I decided to switch to 1.3.1 to see if it would run (I've been updating mods through ckan).  When I switched to 1.3.1 I noticed that there were a ton of new updates available via ckan.  So I ran my updates and launched 1.3.1 but I got a crash.  So I revert (via steam) to 1.3.0.  No dice, I still get a crash.

Windows 7, Steam.

I've read a few other threads that seem to say that I will need to revert to older versions of my mods.  If this is the case could someone explain how to do that with CKAN?  But I'm hoping that it will be just one mod that is causing the troubles.

Thanks!
