I have a mp3 player not a great one but it sounds good to my ears. It can only play mp3 files. It does not support any other file except mp3. I have a lot of my favorite music in wma format. I need to convert these files to mp3. So I downloaded a software for this and in the trial version it would only convert 1 minute audio file. This is of no use to me. Please provide me a link to a free wma to mp3 converter. It should be a full version and should work.
