Do you have any other hardware or applications that synchs when connected to the laptop? Something like a palm pilot, blackberry, etc? I would do the following : close all applications that are running on your laptop - even in the background. Uninstall the software. Reinstall the software. See if that works.

You may have to tone down or close some of the virus protection to rule out that when you do this as well. If this doesn't work I would contact URC and ask then for some tech help. There may be some files that you need to install that either didn't get installed or conflict with another piece of software or device.
