Hey, so I've noticed that lately when i'm using SenseMe, it will freeze my psp and i

I have to take the battery out to turn it off. I've tried waiting until the loading light in the top left corner goes off, but it still freezes. The freezing usually happens when I go to newly added songs and try to add them to my favorites. The song that is currently playing will continue to play even though the screen is completely frozen. Any help is appreciated. 

The problem might be that i dont have the latest version, im a few behind, ill try updating and let you know if it works
