Request help with Pioneer receiver

I have a quick question. My daughter just got a Pioneer VSX-D509S receiver. I'm trying to memorize FM stations that we receive, not the ones that the former owner received. I'm having a heck of a time overwriting the presets already there. I'm following the manual's steps as follows:

1. tune to the desired station
2. press memory button
3. use CLASS button to select A,B or C class
4. use tuning button to select 0-9
5. press memory button again
6. preset number will flash for a few seconds while station is being memorized.

The above procedure does not work. Is there a step that I'm not doing or even a way to clear the current presets so that I can start over?

I have a Elite VSX-41 and it works just as its supposed to.:b

Thanks for your help, I'm getting frustrated
