I'm having this same problem and it's making me very mad, I have AVG and whenever I try and log onto Fiesta I get as far as the select server screen, and then this message pops up.
CODE_FIELD[30-04000-00000000-205]
The game execute file is not normal or an abnormal memory access has been detected.
I would really like to get on Fiesta, any help would be greatly appreciated.
