Presale problem


I have join LPU before the limit date to have access to the presale tickets of the "one more light" tour and I can't have access to them. I really want to go see my favorite band when they will come to Montreal. So if anyone can help me it would be really appreciate because I don't have the presale code and I want to go see them. 

Sorry for my english im french and I try my best in english
