NL User Name and Reg. Key

Hey guys, I just got No Limits Simulator. But I have a question about the user name and registration key that I have to enter in order to play the full release of the game. I had the demo before, but now I have to enter this information..and I have the info, but for some reason when I enter it exactly how I see it, it won't accept it. So what do I do? Can someone help? Thanks, I'd appreciate it.

Just a GUESS... and I may be wrong, but try uninstalling the demo version & installing the regular full version, then try registering it.

It's how I did it when I first got it, and everytime I've reformatted my computer since, I've used a copy I made of it to put back onto my computer & just put my original registration information when it prompts without any issues.

...or there is the chance that the information you are trying to use is no longer active due to pirating...?
