I thought saving a preset manually would be easy, but so far it's impossible.

I got and HD400 for christmas, and have been playing with it nonstop since. I wanted to save a preset that I perfected for an intro to one of my band's songs. I pressed save, changed the name, changed the location to 32A as it was empty, and pressed save again. 32A was still empty. I tried it again, same thing. Tried saving to a different location, didn't save. Tried pretty much everything and it won't save. I went online to the manual to see if I was doing it right and sure enough I was.

Am I missing a step? I know I can just do it on my computer, but I know I'll need to make new presets and edit my presets when I'm at practice, where we don't have a computer.
