Asus ROG 5870 Platinum + GPU Tweaker Not Opening?

[SpectreDev]

Ok, so here's the deal. I've tried all the solutions posted for GPU Tweak not opening, and not a single one has worked for me. GPU tweak will open as a process, and will close. No window is shown.

I paid $500 for this card and every software I've ran into by you guys is lousy, buggy, or does not work. GPU tweak is actually something that looks decent and could be the MSI Afterburner replacement for me. iTracker 2 is awful and destroyed my last Windows installation.

If you can't fix this problem, then can someone give me a software I could use to change voltages and overclock that works properly?

Stuff I've tried:
-MSI AfterBurner
-ATi Tray Tools
-Sapphire TriXX
-Asus SmartDoctor

The only two that have worked are Afterburner and TriXX, but they don't have voltage control support for my card. The other two just crash on me, and don't open.

Thanks in advanced.

EDIT:

I found out why SmartDoctor and iTracker don't work, it's because I'm not using your drivers most likely. You should make your software accessible even without the outdated drivers you post, because what are the chances people are going to use your old drivers over the new AMD ones when there's no performance gain from yours? You should engineer these cards to work with the software with or without your drivers.
