thats what chickHEN is supposed to do. just keep trying and see if it works. you should try restoring default settings and turning off umd cache and umd auto-start like it says in the tutorial. it will take a few tries to get it working.
i would say that if you try more than 20 times you need to try something else. there have been two mods make to make chickHEN load easier. before you try either one you need to remove all files associated with the previous chickHEN load (h.bin and tiffs). the mods will automatically reload these and the old ones cannot be present.
the first mod can be found here:
ChickHEN Mod - Load ChickHEN smoother | ChickHEN R2, PSP Hacks - PSP Slim Hacks
and the second can be found here:

i would try these in the order that i posted them, starting from the top. this should help.
