I sold my MMS I've been using for over a year now and had to make a new one. I used the newest version of PSP Grader, but it didn't work so then I went with Rain's and it worked great. However, after modding the PSP, there is no audio on the main XMB. It worked fine pre-mod and the audio works fine in-game as well. I know I won't be able to sell this thing though if there's no audio on the XMB. Anyone have any idea how I can fix this or at least why it happened?

try reinstalling it?

First make sure that key click or w/e is enabled in the options, and second, copy any audio files you wanted to be used and try reinstalling or maybe using an older version of the program.
