PSP Help!!! (please help guys)

Hey guys,

So here's the thing: I had two games saved on my memory card (demos) and an updater to 3.8. When I upadted my psp the two games were gone from the memory card. Now the thing is that the memory space remained the same. (eg: 2GB before installing them, 1GB after, and now they're gone but the memory is still 1 GB and all the music is still there.

So can anyone help me please? Thanks in advance.

after a firmware update you may need to redownload the games from your PS3/PC to the PSP.

USB mode on a PC should let you find the bad files and delete them if that is what you want.
