Upgraded my Laptop yesterday to Windows 7, Installed DTM 5.0, recognized my Tour. Installed DTM 6.0.1 would not recognize my Tour. Uninstalled all DTM's Reinstalled DTM 5.0 then 5.0.1 Service pack, still no recognition. But the laptop recognizes it when I plug in the USB cable, and Tether works fine! Really baffled if anyone could help, would appreciate it!
