I just upgraded to the newest version of iphysics (1.0.1) and even though I had lots of levels installed, they aren't showing up now. They worked earlier, but I went to play them again later in the day and they weren't there, just sandbox and crayon physics, and crayon physics was the same as sandbox. I went to installer and it said the levels were still installed. I tried uninstalling a few and then reinstalling them, and still no luck. any suggestions?
