So far I have tried almost everything. When I try the current stable version(1.5.1) I get an error that a java file can't be copied. The problem mentioned  here saying it is fixed on version 0198+, but there is currently a lighting bug in 2.0a4 as well as a performance issue with Open GL. This problem makes it run extremely slow and cause increased CPU processing to the point it is not usable. That problem is mentioned  here. I have tried version 0199 but still no success.

Any suggestions?
