Fist of all, thanks a lot for all the help!
I solved my problem!
Fist, I downloaded and installed the crystalspace. Where I installed it, I do not know, bu it installed well, and I don't know if that has something with the solution.
Then, I unistalled completely the PS. I deleted even the configs files and images, all clean. So, I installed it again. I opened the launcher and it upgraded the game.
So, I hit the play button (it took me a lot of effort, 'coz it was barely visible on my screen). The client opened ok, and I closed it.
Then I went to the config file of the client and manually changed the window sizes. The launcher I left the way it was. I started the launcher again, hit the play and the client opened just fine and in a very friendly size. I made my char and the tutorial, and now I'm in game!
So, thank you for all your help and see you in the game!
