My Bluetooth PAN Adaptor was working and after Windows update it no longer will work.

I reinstalled BlueSoleil 9.2.494.0 ver. software to no avail. Device Manager shows yellow triangle and under Properties says "Windows is still setting up the class configuration for this device. (Code 56)" and under Events says "Device {F12D3CF8-B11D-457e-8641-BE2AF2D6D204}\IVTBTPAN\1&1ec31360&a&0000 requires further installation."

How can I fix this problem.
