Hi,
hmm, I'm not running Vista so I'm out of any hints other
than there might be a lot of garbage left behind within
the registry. Try to use CCleaner or a similar program
to remove invalid or dead entries within the registry.
Clean up the temp folder and remove any SE program
folders that had not been deleted during uninstall.
If the problem is still there then either contact GTAC
or your reseller
