SSS getting beep of death?

[linkbean]

So I downloaded the Classic Stage Expansion 5.1 and installed it for Riivolution. It worked fine. Then I went back and tried to edit the SSS pictures for it, but I was getting the error 'the given key was not present in the dictionary' in BrawlBox. So I used an older version of BrawlBox and I didn't get the error. After I finished editing the pictures, I saved and loaded up Brawl with the edits. It worked fine, until I went to the SSS, where I got the beep of death. What happened?
