I've done a manual install using playonlinux. Its a game called Elsword, one of those free online games. After i installed it doing a manual install, it started to run and then those online security features popped up and then i get an error. It said that there was a invalid parameter. Is there anything i can do to fix this?

First thing you could do is check the Wine AppDB, if they have tried that game before... It's allways a good start if you run into problems.

I just checked, they haven't tried the game.
