I try to launch the game but it goes right into the error message, not sure what to do.
As much as I’m sure a lot of people would like to help. You couldn’t have provided less information about your problem even if you tried to.
And you couldn’t have been less helpful if you tried. 
@Obfusca what exactly is the text of the error message you’re seeing?
If the patcher won’t open at all you’re most likely missing some DirectX9 files required by the game. Try running dxwebsetup from the SWL folder.
The difference is they were looking for help. I wasn’t trying to be helpful.
