Is there a way to convert a wma to mp3 with nero?I always get e license issue

You are scary.

Why would you want to do that? The quality of MP3 is even worse than WMA. If you can, convert the original source to MP3.

My problem is that i have some wma files and i want to convert to mp3s because my portable player can read only those files not wma

buy the original cd's OR get a new media player OR try Dbpoweramp Music Converter @ http://www.dbpoweramp.com

1. decode WMA with a diskwriter (for example foobar)
2. encode with lame

(.....IF you really want to do THIS)

Encoding directly wma files with foo_clienc or with foo_lame is probably faster
dBPowerAmp is another working solution for this task.

Not sure if this is legal: If you use Winamp, delete the Windows Media plugin and add the "WMA" extension to the DirectShow plugin. Then, use the DiskWriter output plugin to create a WAV file which you can then convert to MP3, Ogg, AAC or whatever.
