Pearl Ringtones

I've searched through all the old threads before posting this, but I could have missed the answer among them. So sorry if this is a repeat. :o

So I've been using Cell Sea [dot] Com's free ringtone maker to make ringtones from a couple of my CDs.

They are all in mp3 format, so I played them on my computer to make sure that they actually play (which they do). Then I use Desktop Manager to transfer the files to the blackberry. When I try to play the ringtones on the blackberry, that's when the problems arise.

It worked well on my blackberry for the first few tunes, but then when I tried to add other ones, they don't play at all (It can't be due to memory issues.. I have a 1GB). Sometimes the phone even shuts off by itself when I select some of the tones. :eek:

Can anyone help me solve this problem? Do you guys know any programs (free) that will allow me to working ringtones for the blackberry from my CDs or any other audio files?

Thanks in advance!

Maybe it's to do with the way the tones were made. Do a battery pull, then go here, to get a few, and test those...
