Thank you so much for replying.I am on windows and it is a video/audio file. I am new to computing and do not understand a lot of the technical side of things - if it doesn't work I am stumped!!!!! What do I do now?
It is in I Tunes a MPEG-4 audio file.
Our daughter used the computer last year and made a video for a 40th birthday
the music went on then with no problem but she could not do it this time.
