The Game doesn't start

I just Downloaded the Game and patched it but everytime i click on start nothing happens. I already changed the Neuz.ini , i already created the WdMarket folder , i already deleted the Neuz.exe and patched it again, i already changed the settings on Low. Are there any other things i could try? Scratch all that above its working now but how can i change the resolution now? and Thanks for the Help guys

Disable or include Mazey Flyff/neuz.exe to your firewall and anti-virus exception list. If that still doesn't work, delete Mazey flyff folder and re-extract the whole client.

What Pinki said. But before you resort to patching the whole client again, try editing the compatibility of both Neuz.exe and the patcher at Properties>Compatibility tab to be compatible to WindowsXP (Service Pack 2). Or something like that and run the program as administrator. If that doesn't work, try repatching.
