I think it it would be easier for you to:
a) Find someone here who has a cable - they'll help you.
b) Buy a genuine RossTech cable. You might get one on ebay for less than a new one. They are a wee bit expensive, but you know it'll work and you'll have all software updates etc.
Piracy isn't the best and in your case is costing you money!
Having said all this it's only my opinion of course, I'm not here to tell anyone what to do.
