Hey Gy,
did you get it figured out?
If not, what exactly is happening when you start up the launcher?
What operating system are you on?
have you deleted the files that are mentioned in the startup guide?

step 3 is probably the most important making sure you don't patch the game.
make sure you're on version 42 for the files that can be DLed from the same page in step 1.
post here if you are still having troubles and don't forget to google, or search this forum as well, many problems have been faced and solved right here already
