Cant seem to prevent this error?

Which web browser are you using, and what country are you signing up from?

Internet explorer.
Signing up in Singapore but using American proxys.

Only times I've seem that error is when I try to create more then 2 mules on the same day. Apparently, though, if you use a browser with Firebug or similar like Google Chrome, you can change the hidden form field "idMachineKey" (populated by JavaScript) and it should work just fine.

I do remember one of my computers having Google Chrome, I'll try it out sometime soon and post the results

Internet explorer.
Signing up in Singapore but using American proxys.

That could be the problem. Even if you use a proxy service for an American based IP address, Nexon could be detecting the proxy as an invalid, blocked, or previously banned IP address. You might be able to change proxies and try again, but if not, then you might be out of luck.
