Hacking Psp 2000 6.60 Pro B-10 stopped showing homebrew apps, Help?

[eusc]

My psp 2000 with 6.60 Pro B-10 just stopped showing homebrew apps and games. Its not the ms because its still playing music and loading saves for my umds. It still shows the system as being 6.60 Pro B-10 and I can access the recovery menu.

What do I do?

Upgrade to 6.60 Pro C fix 3... Duh.

Do I have to downgrade to official 6.60 or can I upgrade directly from pro B?

I think you can do it directly, but you will have to CIPL flash it again to make it permanent.
