I have P4 and I get that error mssage sometimes what I did to stop it was, delete the useless items that I'll never use, like the child figures in P4. I basically use M3 & V3 now. I uninstalled some of the characters and it seems to help P4 load faster. For myself, I'll never use 90 percent of the old content P4 loads. Best to try to reistall. :) (JMHO)
