Well, it looks like one of your idStorage keys are corrupt, try to fix it using KeyCleaner. Here's what it says on an old qj forum post:
"DRNFFFFFFCD = key 0x5 header is not "g k l C" (in hex: 67 6B 6C 43)
* to fix this, get KeyCleaner - then let it clean key 5, run it again and tell it to UNPATCH key 5."
You can download KeyCleaner by searching on Google (I can't post links since I'm a newcomer), but I suggest you to stick with 6.20 since using KeyCleaner might brick your PSP and the PSP that you're using (3000) is really hard to unbrick (the method is called Baryon Sweeper), but if you want to risk it, go for it.
