Men of War Online trouble

[M.Wagner]

Im a huge fan of the series, im not going to waste your time so here is my problem:
When I got the game, I could play perfectly both, the campaign and the multiplayer. Once I had erase everything in my pc because it was really slow and when I reinstalled the game it tells me that there is an account that is using my password. I also got another problem: it had been a long time since the last time I played and i don’t remember my online account.
I know it’s a long shot but im really worried as i spent my money in a game i really love. If it is of any help I can tell you that my old email was nicomw3@hotmail.com (they closed it because of spam) i got the original game (the disc) so i have the code,the serial,etc.
Thank you for your time.

PS: Sorry for my grammar.
