I have un-installed everything and started again, but no different. I to am running Vista, and have tried it as adminastrator and normal double clicking.
I also thought I would go back to an older version V1.32 and re load older mod software on, but I get a warning saying "this software cannot be upgraded"
It looks like the software upgrade has ruined my GT 2.0 speedo.
Really, really stuck now!
Any ideas anyone????
