Ok first let me say i'm sorry, i'm sure this has been discussed at great length but my searches have failed to turn up a fix for me. so here we go...

This weekend i recorded my little one laughing his little head off using voicenotes. I emailed it to myself not realizing that it is a .amr. So i serach here for .amr to .mp3 and i found that mobile media converter. Cool i think, i'm on the right track so i convert it and it plays on my PC but when i use Media manager to transfer it back to my BB all i get is a file that won't play. What have i done wrong here? I used the guide at the FAQ site to tell me how to transfer. It shows up on the BB but won't play.
