New to Virus ti and virus control

[Trancehead]

Hi,
Problem I'm having is that access say the serial number on the sticker under my second hand virus is not a valid serial number, and so they won't let me register to download the updates.

I bought this virus ti second hand and it is running version 3.0.1.15, do I need to find this version for my mac and install that, or can I use the disk that came with it and revert back to an earlier version (and is this recomended)

I'm confused, i love the sound of the virus but...... I was recording/saving patches with my v-synth within 2 hours, I've had my virus 2 weeks and am no further forward, the whole point was total integration

help

Make sure you enter the serial excactly as it apears with the capitals letters capital and lower case lower case.
