Your vista must have been a 34 bit OS. The mobilelink (for Alltel) is not available for 64 bit systems. I have not tried to bypass the program by setting up without the usb connector and the software through bluetooth. I do connect my 32 bit laptop to my LG 8600 phone using Bluetooth, (my usb adapter bit the dust) but I use my axcess software.
Interesting. I will try to use it at home with 64 bit this coming weekend.
If you can connect your phone to your laptop via bluetooth, try then clicking on the phone icon in your bt folder, this should bring up a dialing box. Your ID or name is your 10 digit cell phone #, the password is alltel, all lower case, the number to dial is #777
