Even if you do have problems with starforce, if you send Larian the error report from it, they will send you a "authorisation file" back which will make starforce bypass the normal checks. (its only valid for the one specific Pc you installed it on).
Starforce is "fixable" if it doesnt work on your system for some or another reason <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
