MBL Files Won’t Open or Show Up in Custom Looks

Hi!! I recently updated my Magic Bullet Looks Suite to 14 which lead to all of my custom looks disappearing and being removed from the "custom" folder. I managed to download them again and place them back in the proper presets folder which should have made them show up in the app but they never did. I use MBL on After Effects by the way. I've tried to uninstall and install MBL but that never worked. I'm not sure what to do. Please help!!
