Starting Compiz in 7.0.4

[Mark_Twain]

UPDATE

7.0.2 DVD downloaded U.S. server -- no compiz, no connection.
7.0.3 DVD purchased OSDisk.com -- no compiz, no connection.
7.0.4 DVD downloaded German server -- no compiz, no connection.

However, this morning I downloaded the 7.0.4 CD and it works perfectly. Compiz comes up and the connection is automatic.

Something on the DVD is different from the CD.
