Stolen Account

Hi guys, i used to play this game about 2 years ago, then my account got stolen and i failed to retrieve it so i just stopped playing.. Now i want to play with my friend, however he is on this server and i can not make an account there anymore as I am from Czech Republic.. So now i would like to get my account back - i do not know what the email is because the player who stole it changed it. I do have many replays with me playing, do remember the name of clan i was in, do remember a few friends i had on the account (he deleted them from my account but my friend still has me in friendlist), im not 100% sure if i do have the security answer-there are 2 possibilities but one of them is 100% correct (just the same answer written in 2 different ways).. also have some screenshots... i moved to a new house and dont remember IP address.. so i wanted to ask you, is there a chance i will get my account back, and if, how ? thanks for any help or suggestions..
