Heya, sorry for the slow reply.
Well, then there are other things you can try.
Two things, goto the BT or UT icon and right click, goto properties then compatibility, then check the box that says ' run in compatibility mode', then pick, 'windows XP sp2 (service pack 2)'. Then click OK.
Try to run the program again.
If it still doesn't work, then right click and click 'run as administrator'
then see if it works.
If it still doesn't work then i'm not sure of anything else you can do. Let me know though.
