Ive just found an old freebie I got from one of the threads here, an Authenex A-Key.

Quite cool little thing, but problem is I cant find the software that you use with it anywhere!!! Any ideas?

Seems like you have to pay for it?
I think I still have my key somewhere too...

well it was free as part of an "evaluation kit" but had to download the software obviously. Bloody things.
