PSNabler final doesnt work for me

Hey im trying to play resistance retribution w/UMD online with cfw 5.50 GEN-D3,as you all know(if you have it)when you just start it up it has a skull with guns crossing (its also spinning).But when i turn on the PSNabler_FINAL it crashes and just reboots.Here is another thing,while I got the folder where i was supposed to copy it to my GAME folder it came up with 2 "ms0:/seplugins/psnabler.prx 1" while i was supposed to have a .txt file with that.I've tried almost everything i know about psp hacking but nothing helped.So if you can tell me how to work it,please explain in detail.Thanks in advance

did u make sure the fw in the txt file is correct?????

where u hav the fake ofw type in 06.10 instead of 06.20
