cant login my old account

Hello i dont why but im having a really weird problem with the last account i had. i had to make this account so i could just make this thread. I dont know why but i cannot login the last account i had for WoW. i played with it on Molten-wow.com. Now i know that Molten was converted into Warmane but have no idea what happend to my account. it had all my best characters and its really sad that i cant access it. I went on a big gap from playing WoW but i knew this much that Molten was converted into warmane so i seriously have no clue what has happened. so can u please help me and explain what is going on and what happened to my account and what should i do.

there has been a problem, "Molten-Down", some guys from the past Staff has deleted everything and everyone lost their Account and Characters, more info if you type molten-down on google
