Serial Key Generator Mount & Blade Key Generator Problem?

Key Generator problem? - serial key generator mount & blade

So I installed the program (AutoCAD) and when I put on the login page in the serial number, and throw the key generator ... an "internal error # 1" sign appears and says to be that the license application and the screen so far .... they are. Who knows how to fix it!? School starts tomorrow and I can not live with CSA!
