When I run SWTOR Unleased and go to ether settings or about it will cause a SwtorUnleashed.exe has stopped working error and then a second window will occur and ask "Do you want to send more information about the problem?" and if you hit cancel, send information or click X the program closes.
I have windows Vista 64bit and Framework 4.5 also ive even installed 4.0 and still did the same.
