Eseries / Communicators :: Nokia E72 Alarm Ringtone - No Longer Customizable?

I've had my E72 since July '10 and everything's been fine, but recently something rather odd happened. I don't know whether it would be connected to the problem in the title of this thread, but I woke up yesterday - after leaving my phone on, as I always do, and it was pretty much fully charged - and the battery was drained, and my recently dialled/received calls had disappeared. As strange as that was, I dealt with it because it wasn't a huge deal. However, I have since discovered something else.

I changed my alarm ringtone from one of the many ones I have manually put on my phone to off, so I would just be woken by a vibration. Upon trying to put it back to my custom tone, as I have done hundreds of times, I've discovered that all of the songs that I've manually put on my phone don't come up on the list of ringtones available for my alarm, which I find odd. Only the default/preset ones are available.

I quite liked my alarm tone, it was the song used to wake up the characters in Inception!
