dlvette,
Download the drivers for your wireless adapter and save them to your desktop.
Make a system restore point.
Start, control panel, device manager, network adapters, right click on your wireless adapter, left click uninstall. Tell it to remove the drivers and software.
Restart your computer.
When you log back in, the new hardware wizard will try to install the adapter but fail. Then install the drivers from yuor desktop.
Happy New Year, I still have 8 1/2 hours to go. 
Rick
