hi yes, thats exactly what I did.
loaded the hack but didnt seem to register, re-started machine, plugged the lead in(from ebay seller) and re tried the hack, checked the vag-com details and it says its fully registered/activated. thats the easy part the difficult part was figuring out getting the inetrface port sorted on my laptop, cos the instructions from the website are pants.
good luck, b a shame if you cant get it sorted when you put me and others onto this!!
