Did you purchase LPU 11 or LPU 12? We are currently on LPU 12, which to my knowledge should have been the only one available for purchase. What is the error message you're receiving?
I purchase LPU 11 and I got a pass code sent by Email but it is invalied
Can you send me a private message with the date you purchased LPU 11 as well as a confirmation code/number? I'll look into it and see what I can find out :)
