Managunz black screen on startup

Im running 4.92 hen with the latest version of managunz and file manager homebrew. The file manager works perfectly fine but nanagunz just freezes on a black screen when i start it. Ive already set fan to syscon and uninstalled webman mod and it worked once but now its freezes again every other homebrew app i have works no problem. So does anyone know a fix or another reliable way to run ps3 iso backups?
