I've tried that and it didn't make any difference. When i do finally get into the game, its running at 0.27mhz (at the bottom of the emu) and I know this can't be right. I have even tried the new beta version and thats no different.
Sounds like that Mastercard scam that went around a few months ago. Someone I know got a called from someone saying they was from Mastercard and they seemed to know all about my friend.
Basically it ended up with my friend giving out there account number and before they knew it, there was unexplained transactions on the card up to the value of £1000.
All I can say is beware and keep all personal details exactly as they should be.... personal. In my opion, any legitimate company would already have these details anyway and wouldn't have to ask for them.
