Okay i am trying to play on a runescape privet client and i cant open the jar file. I already have moparscape client downloaded and it works fine but when i try to open the countless other clients out there I get the "check console for error" thing. First of all i am completely computer illiterate. So i don't know what a console is or where to find it. I am confused, i mean if it works for one client why doesn't it work for the other. Please help me thanks.
