I would use the cab file I attached, (Can't remember who made it, but credit to them!) soft reset, and use the Internet Sharing feature in WinMo. It's much easier to get along with most computers. No need to setup, just start internet sharing, select usb from the drop down and tap "connect" at the bottom. Then plug in to your computer and go.
Or if you're using bluetooth, pair it to your pc, then use the "Join Personal Area Network" by right clicking your bluetooth icon in the system tray of your computer, and you're good to go and gone!
Edit: You must have Active Sync 4.5 (if on XP) or Windows Mobile Device Center (if on Vista or Win7) already installed. For good measure, you need to first let your phone connect to one of those, then disconnect and give my instructions a try.
