I have a Blackberry I was trying to setup for someone last week and I keep running into a problem where it asks me for driver files.

I don't have a CD for it.
It's brand new and was tested on another machine with the same OS, works fine. When I attach it to her laptop it sees the blackberry but prompts for drivers that I don't have. I look in device manager and see two Blackberry devices flagged(one says Blackberry and the other is RIM). I installed the software the way I usually do. I checked and deleted any other blackberry software.
I had some techs recommend other things to me. One suggested removing everything RIM-related from the registry, and another guy told me to try a chkdsk /r. The latter I haven't tried since I don't know if that would help, but I'm open to any other suggestions.

I'm trying to see if I can download the software and install manually from the sprint site. Don't know if that will work though, as my company provides me with the driver files for stuff. They had the 8330 software on our server which I installed, but it didn't help.
[edit] Oh, and I got the model wrong.
