Vista - MobiLink Network Connection Manager...

...doesn't want to work with my computer. My internet card can't run on my computer without it. T.T

I have a Gateway T-6836 laptop that runs Vista Home Premium 64bit and the card I'm trying to use is a Novatel U720. I've installed and reinstalled this program many times trying to get it to work but it always does the same thing. I launch it and it immediately comes up with...

MobiLink Network Connection Manager has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.

I've tried
-running it in Safe Mode.
-installing it on the admin account.
-actually following the directions, lol.
-calling tech support. Twice.
-using the software from both the included CD and the website.

Any other ideas? What could be causing a problem like this? I just got this card on Sunday and I've been working all week trying to get it fixed. Halp?
