I have tried with 4.0-652, which I believe is the newest version for netplay, but I ran into the same problem. When I did that, however, I noticed the settings folder located in ~/user/library/applicationsupport/dolphin does not disappear when I delete the actual application. Could that be causing the problem?
Also, how do I check to see that the games aren't corrupt?
