I havent been able to load the desktop client for a while now on my PC. When I click rscrevolution.rar a java window opens and closes straight away. Dont know whats to be done fs.

Try this, I have to run the launcher this way in order to play.

1) Open a new text document and paste in it

@echo off
start "" javaw -jar Launcher.jar

Be sure "Launcher" is whatever your downloaded launcher is called.

2) Save it as a .bat file (run.bat) by selecting "save as type" then select "all files"
3) You should now have a batch file on your desktop, run this and the launcher should fully work

Hope this helps, if not let us know
