audio conversion/ogg vorbis HELP

[jd contratto]

Hi, fellow reporters,
Don't know if I've already posted this -- been asking for help everywhere -- but has anyone downloaded ogg vorbis on their software for their audio? I downloaded a version of it, which turned out not to be the authentic version, and now, because I switched laptops, the files won't play on my new laptop. Can't use the old laptop because my wonderful husband reformatted the hard drive. AAAARRRRRGGGHHHH.... If not, is there a way to convert these audio files? thanks in advance for any tips/suggestions/commiseration.
