Umm, I accidentally didn't just add that ";c:\Program Files\java\jre7\bin" at the end of the Variable Value, I replaced the hole thing with ";c:\Program Files\java\jre7\bin". Is that really bad? Yes, I know I'm stupid, I didn't read you post carefully enough. Now I just wonder, have I damaged my system in some way? It seems to be running fine...
I had the same problem and found this video really helpful: http://www.youtube.com/watch?v=03W0k_4yvxQ&list=HL1342194912&feature=mh_lolz
But there the problem is solved in complitely different way.
