Had this problem with WiiFlow and Mario Kart. I deleted the game from the HDD. Originally i installed it from disk thru Wiiflow. Redownloaded the game and used WFSB Manager to put it back on HDD. Worked for me. Worth a try for you i guess.
Yeah, the problem is I have 3 different games on my HDD but not one of them works- they all do the same thing.
Does anyone have any idea why I'm unable to load the rev21 update as explained in my previous post?
