I cannot login to mojang.com

This morning, I tried to login in to Mojang.com to claim my free windows 10 edition of the game, I followed a tutorial and it said to register an account. So I pressed on register and it took me to Minecraft.net, The website knew I had already bought the game, but I was not redirected to Mojang.com. Assuming it worked, I tried logging into Mojang.com, It gave me invalid credentials. SO I tried logging into Minecraft.net with same exact credentials and it worked. I cannot figure out why it doesn't work. Minecraft name: MrFloops
