First create a file in your default Star Wars Galaxies folder (IE: C:\Program Files\StarWarsGalaxies) called "user.cfg".
Then edit the user.cfg file with notepad. Add the following lines:
[SwgClient]
allowMultipleInstances=TRUE
After you add the above to the file, save and close it. Then, right click on the file and mark it as read only. (*edit* Important: if you don't make it read-only the game will just copy over your change.) Now run your game like normal, and load into the game world. Once your first character is loaded into the world, load SWG again the same way, only login with your other account.
