2012-11-21 08:14:30.871 E BookHistory loadFromFile: not enough symbols
Seems we are hitting the wall with PRS+ even without running AUTORUN Apps
Kartu what do you think?
You can try to run a beta-pack.
To build it run "ant build.beta" in the build folder.
Place resulting folder Beta in IM.
Next step remove some addons/core components like
/addons3/ App related like Chess, FiveRows a.s.o.
/addons3/SaveNotepadData.js if you don't reley on the functionallity
disconnect form USB and see if this frees up enough symbols to enable PRS+
