Serious Java and SonicStage issues???

[ventusrocks]

I used to use JPCSP almost problem free; Java and SonicStage worked great and in sync. Then, I installed a hard drive into my computer (from a "dead" computer), and it has Windows XP on it (the drive I was using for JPCSP had Windows 7). Then, I install SonicStage and Java separately on the "new" hard drive, and then I play the game; works fine (all of this on the newly installed drive). Then, I play it on the drive that was already installed (which I'll call the "old" drive), and the music/SonicStage doesn't work anymore! Since then, it never really has worked; and I've tried new versions of JPCSP, deleting TMP files, changing UAC (User Account Control) options to allow everybody to use Java and SonicStage (Sony) program files, and also with the JPCSP files. Still, SonicStage doesn't work, and my games crash MUCH more often than they used to (especially when it gets to parts that require media). So did anybody have any ideas about how to fix this? I also tried it on the "new" hard drive; SS still didn't work I will do anything except reformat my computer

Attached is the profiler.txt of a fight with Vanitas in Kingdom Hearts Birth By Sleep (US). The game crashes right after the cutscene where Ventus knocks the keyblade out of Vanitas's hands (right after the final fight in the game). I don't know what the problem is (I used to breeze through this part and be able to listen to music, which I couldn't while I played the game just now), and any help will be appreciated.

Thanks in advance for any and all help!
