Remedy i'm sorry but after reading all this, you transfered a license illegally. If you did it through Vbulletin the e-mail WOULD have changed and you wouldn't be in this problem.

At the end of the day you have one option, refund theodor his money or your reputation will go down the drain and pretty darn quickly might I add. You have money for a service you're not providing. I would also have a word with your friend, maybe ask them for the money back?
