I did the repair installation for windows. SWTOR still won't open.
Can you run this and send it to me in a PM (not on this thread)
want to see if can see anyting out of sorts
Do you want the speccy text file version? Max I can PM you is 60k characters, and the file is way bigger than that? I don't think I can add the file as an attachment. I can e-mail it to you if you like.
File should be able to be attached as an attachment
