    i've never heard of a bobbin case wearing out but i guess anything is possible.
    i would check first, though, to make sure you have it installed properly in the machine. it sounds like it might not be fully seated.
    check also to make sure you haven't accidentally loaded the bobbin incorrectly.
    i've done that a few times and the results are never good. LOL
