Not sure if I am in the right place but when I installed TweakScale from CKAN I messed up with the directory and copy/pasted all my mods to the correct one. I booted up KSP, then the Houston we have a problem window showed up. I pressed okay and loaded it up, and it was there again. Did it 3 times and then tried CKAN. Nothing worked. Afaik I have no incompatible mods. Also it stops loading around Sqaud/Parts (I think)/MassiveSRB(I think), which could be tweakscale,but I doubt it
