Sorry to hear. Hopefully he'll come through in the end, but if you paid with Paypal you should file a dispute if he doesn't report back in a few hours. To be honest, looking at his selling thread, I do find a little suspicious the fact that his "proof" image is hosted in some other forum, like it gives me the impression he could've simply copied and pasted the ad from another forum. This doesn't mean anything of course, it just rubs me the wrong way. Let's hope you get your license soon.
