First find the latest version of Aura and download.*
Then download and install Ccleaner
Use Ccleaner to uninstall then navigate to the programs folder and delete the aura folder that was orphaned.
Return to Ccleaner and run the registry sweep and fix the orphaned registry entries.
Reboot then install the new copy. Should be good after that.
Make sure you don't have any conflicting software like the *version that comes with the graphics card. If you do follow the same steps above to uninstall that too before installing the latest version. IIRC I had to look around to find the latest version. Wasn't on the Formula page.**
