Hi Zarlynn,
Welcome to the eForum from all of the team.
When looking at this question we do need a little more information.
Can you let me know what version of Operating System you are using?
If you are using xp please select Start - control panel - select Category View - system - hardware - device manager
If you are using Vista/windows 7 please select control panel - system - device manager
In here please expand the sections for drivers and modems and let me know if there are any esclamation marks or question marks next to the Vodafone USB Modem drivers.
If you can do this and then get back to us we will see what we can do.
