Dude, im pretty sure that it's been mentioned how to fix it in this thread..
But, if you go to Task Manager there should be a task in there that if you end task in the process tab will quit the application (Stupid hack that you willingly downloaded) and if you restart warrock it should run!
Update: the task you want to end is 'egui' End process tree would be the best option to select.
Hope this helps!
