I bought an SD Media Launcher an a 2 GB SanDisk SD Card. I have configured everything as I have seen it in a YouTube video . I used the old version of the Siwss , which was included in the Download. Most of the games have worked. Now, however, I wanted to try the SWISS version r296 , since I have disturbed the tone sounds in Super Smash Bros Melee . But here is my problem. Everytime i want to boot a game i get a blackscreen. Wether it is Super Smash Bros or anything else.

Can someone help me ?
Sry for my bad english
