rFactor has stopped working

I have installed a new mod and whenever I load up rFactor it comes up with a message saying "rFactor has stopped working" It just appears to be this mod that's causing the problem. I installed some windows updates prior to this and I uninstalled all of them thinking that one of the updates was causing the problem, but I was mistaken. The strange thing was that the same mod was working the previous day. I was running rFactor as admin on both occassions. Any help would be much appreciated :)
 
I also uninstalled a few programs yesterday which may have something to do with the problem. Although none of them have any relation to rFactor, I'll name them anyway: CyberLink PowerDirector 11, WonderShare Video Editor and My PC Backup. I have also tried completely re-installing rFactor but that seemed to make no difference.
