Problems with WMA file type

Hey there.

I got some audio files from a site, and they were in WMA format, I tried to burn the files with Nero but it said that it couldnt read the files. Then i tried to convert them to MP3 with my ripping program (CDex) but it just went not responding after the file was done and the file doesnt play. After that i went to CoolEdit PRo and tried to open the file but it doesnt recognizes it and cant play it. On the other hand, WinAmp was able to play it.

what should i do in order to burn the files to an Audio CD?? what software do i need?

you can use nero to burn wma to an audio cd but you need an extra plugin.
