I had a lot of trouble getting my virus to work after trying to install OS5 and had to wait a few days for support to help me out on that... I will wait for a release version before i try OS5 again.
I have the original TI so not a TI2 and it failed the installation and every retry it failed and started a so called rollback but nothing rolled back and my computer not even recoqnized the TI anymore.
I was really afraid i bricked my synth but now i have it working again don't have the balls to give it another go. I run on win7 X64.
exactly that´s the problem. i even have bought a pc configured for music
