"Rohan Online Game has stopped working"

[Kety]

I'm a returning player, used to play since beta till 2011.
Can't remember ever having mass crashes even with many clients open before.
Yesterday I downloaded the game again and attempted to make Rumir, but not before my client crashed like 20x on several places, starting with login screen, server screen, character loading screen and finaly loading the game...
After all that hastle I managed to get in game and get my new mar/rumir to 51, went to sleep tried to play this morning again...
more than 50x crashes, and I haven't been able to play today at all.
90% of the crashes happen when trying to log in, rest in server and character screen, that's as far as I got today...
Tried several suggestions that people shared here on forums and google and youtube but there is not much, is this problem uncommon?
I also disabled my antivirus cause it kept saying there was a problem with rohan.
I tried both loader and launcher straight.
I have windows 7 64 bit system.
I really doubt it's my PC, because I never had this problem ( same PC as 2011 but tweaked ) before, and I can run newest high end games at max graphics with no problems, my internet connection is stable, so I'm really confused now and out of ideas..
