[RESOLVED]Cannot update drivers in Windows 7 x64

Tried updating driver to 5.0.3 and it won't load device anymore. Firmware updated could not detect virus. Virus Ti Audio shows up with yellow exclamation in device manager. I managed to connect it to my old Mac and was able to update firmware, but it still doesn't work in Windows.
I finally managed to do a system restore and driver seems to be working however VST now not compatible with 5.0.3 firmware What a mess!

Thanks I did
But I just found solution/workaround. Well all it took is getting rid of Windows 7 and Upgrade to Windows 8. But I was able to upgrade driver and software after that...
