Irshell Help

I just downloaded and installed Irshell on my 1.5 psp. I put the remote files in the correct place. (Memstick:\PSP\GAME\IRSHELL\IRCODES\Codes\) I assume thats the correct location since the zip folder layed out the directorys already, but the codes don't show up under Ir Remotes in the shell. I've read the Faq on the Irshell site and it didn't help, all it mentioned was turning "Hide RDF Sub-directory" off, but mine was off by default. How do I get these codes to appear in the shell so I can use them?

Press [] (square) untill you come up with the ms0:/ screen, which looks like this:
_____________________
_______ms0:/ _________
.. <DIR>
IRSHELL/ <DIR>
PSP/ <DIR>
etc.....

then select the subdirectory "IRSHELL", then "IRCODES" and voila, your codes are inside that subdir "Codes". Easy.

Move the IRSHELL folder from the PSP folder to the root directory and it should work fine.
