Another idea: get an entirely fresh machine (laptop/VM) that never knew anything of your clinic/sensor before. A Windows machine, that is. Install a freshly downloaded version (say, a trial version) of your imaging software (or of another software documented to support your sensor). Plug in the sensor and monitor the USB flow. Since on that "machine" you never entered any license key material you might be able to obtain untainted traces. Karsten
