game could not be started (800200E4)

i was just tweaking abit...basically playing around with eboots and this message popped up...

Game could not be started
(800200E4)

Any1 know what the error code stands for?
I only know these few but nothing about 800200E4
80020130 - File Read Error (ex. length is 0)
80020001 - Generic Kernel Error - default (ex. executable is invalid)
80020148 - PRX type unsupported / Missing PSAR file
800200D9 - Failure to allocate memory block (ex. missing PSP)

What firmware do you have? Also, what kind of Eboots do you have, like KXploit, etc?
