Ok, I just installed VBRun6sp5, it's actually the same that needs to be installed for MAT Pose Edit to work and still nothing, so I don't think it was a matter of not having the correct Visual Basic files, especially since I've been using MAT Pose Edit all this time. Guess I'm not going to take my chances on the UTC either. Unless someone out there has had the same problem and can shed some light on this by Monday ;) Thanks for your help and time.
