Tom Tom Home V2 Not working

Hi

Aplologies if this has been posted previously.

I have the dubious job of updating our office Tom Toms. Today, I plugged one in and was promptly told to update my version of Tom Tom Home, prior to doing this the earlier version of Tom Tom Home worked just fine and recognised there was a Tom Tom plugged into my usb port.

I installed the new version of Tom Tom Home (v2 or 2.1) and it will no longer connect to the device, worse still, the device itself will no longer recognise the SD card.

Is anyone aware of where I can download the older version of Tom Tom home?

Thanks

Should be on the original CD for the TomTom
