SO maybe I bought the wrong software. What I am trying to do... I often download music from bt.etree.org or livewidespreadpanic.com Recently while out of town I guess my computer crashed (?) a "friend" staying at my place downloaded all these trial versions of things that would allow me to continue to download. It was all working fine. Then the trials expired. So I purchased all the software online that I thought I was using as trial. Now nothing is working. I have these shows (live concerts) downloaded and it looks like they are in a wavepad form (has the little wavepad logo by each download. I am unable to play or burn these files. Is it the software or the user and what can I do to get my music? Do they need to be converted or something? During the trial use I had to do nothing I just dragged the same kind of file to my nero7 burning software and It was good to go. No problem. NOT anymore. Spent hours trying to figure this out...Please help.
