Wow, we think alike, a bit. I tried launching the CK directly from its executable instead of from MO and it won't run. I mean nothing happens at all, no error messages, it won't even open a window or anything. I tried removing the CK's files from within Steam and then re-installing it, but that didn't do the trick either - the problem persists. I do agree that there might be a connection between the error message and MO, but I won't know for sure until I can get the CK to run outside of MO. EDIT: Oh my God I'm an idiot. I installed the CK to an old drive where my Skyrim install used to be, and not to the new one. Well at least now it starts. Now to see if that fixed my script problem as well.
