Starting Compiz in 7.0.4

[Mark_Twain]

“All files OK.”

I downloaded 7.0.2 and 7.0.4 and md5 sums checked. I also bought the 7.0.3 DVD from osdisc.com. None work correctly for me, no compiz and no connection (although I haven’t tried too hard to get a connection). Same hardware -- 6.4.3 works fine but none of the 7.0 work.
