I think you're the same person from the GameFAQs board that posted in my topic about this too. I'll post my answer here as well, not sure which site you check more.
Go to Settings->System Settings->System Information. The System Software Version is what your OFW is. OFW is official firmware, which is what Sony's updated the PSP with. CFW is custom firmware, which requires a software modification to do for the PSP. Odds are you have the official firmware, which is why the patch isn't working. You'd need to install custom firmware to do that. I'm new here so not sure what the site's rules are in regards to the modification of the system, but if you check my thread on GameFAQs that you posted in, someone there helped me out a lot with it and I was able to get the system modded with the info they provided.
