DongleRead.exe is a program that verifys your dongle and displays the Serial Number. Its on TM CD and also in the TM Folder, This will prove the Dongle is connected OK. However I have had similar TM problems where I got the message the dongle is missing, It seemed to be caused by a Windows Update, I resolved it by reinstalling Windows and the Reinstalling TM, There may be an easy solution but I havent found it yet.
