I can't login at minecraft.net and the minecraft launcher, but I can login at mojang.com

I don't know why, but I can't login myself at minecraft.net and the minecraft launcher, but I can login myself at mojang.com.
At the launcher it says "Login failed. Invalid username or password.", but I'm sure that I used the right password and on minecraft.net it says "An error prevented your request from being processed. Please try again."
So I just wanted to know why I cant login at minecraft.net and the minecraft launcher.
A bot said my launcher is pirated.. I don't know how this should be happend.. I purchased Minecraft from the minecraft.net store on the 24th of December in 2014 and I put a screenshot from my account at mojang.com!
(Please don't say that I have to check my e-mail and password! I tried it on different days and I changed my password a few times!)

Thank You!
