same problem !
I´ve got the same problem with Fast Track Pro.
When I boot up my System (Vista 32 bits SP1), a PopUp with "TBIA - Zugriff verweigert" (German, means "denied access") appears.
I´ve connected an USB HUB (it is recognized without problems), and I tested it on every USB port of my notebook: same problem.
I also tried deinstalling FTP drivers, reboot, and installing them again, but seems not to work.... please help us !
