HEllo Akinyemi and welcome to the eForum
It sounds to me as theough there may be too many instances of 'modems' in your Windows modem list, please can you try to do the following:
(please note this is an XP layout but should be similar on Vista)
1. Start
2. Control Panel
3. Phone and Modem
4. Advanced tab
5. Remove any modems by the name of Huwei or globetrotter
6. Restart your computer and try to run the software or plug in the modem.
Thanks
Reidar
