bluetooth wont connect to mindstorms

[computerbuildin]

I have the earlier version of nxt, not the yellow brick but the one right before the new 2.0. They will connect to eachother and say its successful, even the mindstorms says they are connected, but they cant communicate. when i go into mindstorms on my computer there is no devices. I went online and found out the driver provider has to be microsoft or widcomm, mine is motorola. Is there any way i can change this or am i forced to buy a new bluetooth dongle? I actually have one but i plugged it in and it wont even start up so i guess we throw that off to the side.
