Linksys WUSB11 v2.5

Hello, I had a USB adaptor working and then tried to
update the driver. I now get the following error.
"There was a problem installing the hardware
Instant wireless USB network adapter v2.5 #9

An error occured during the installation of the device

The name is already in use as either a service name or a
service display name.

The folks at Linksys tell me that there is something in my
regestry that needs to be removed.

Any thoughts?

Thanks

Lou
