Hmm. But have you formatted it after inserting it into your phone, if not then do that as mentioned above. If the problem still persists then at least you can be assured that it was not the size or class of the card that is causing the problem.
In my case I have now formatted the card in the phone & assigned custom ringtones to individual contacts only & not to groups as I had done before. And it seems to be holding up as of now
