I bought a Volvo Vadis DVD 2002 Edition C (US English), I live in Scotland and bought it from a guy on ebay in the US. When I try to use it it gives me an out of date message and also asks for a username and password. I can fix the out of date message by resetting the clock on my PC. Does anyone know what the username or password should be for this? The seller on ebay hasn't been any help.
