Burning a CD - wma to mp3 -*EMERGENCY*

[Fallen]

Hi.

Problem: I'm trying to burn an MP3 disc, but (most of) the files are WMA files... seems a simple problem, but I cant seem to do it with Windows Media Player and my CyberLink Power2Go is trying to make me buy an add-on to burn a disc with more than 20 MP3s ...what I was thinking is I could make a data disc to get around the 20 Mp3 limit... but I dont have a file-converter for wma -> mp3 ....

sooo... my main question is should i get a wma -> mp3 converter and burn a data disc with my current burning program? if so, where can i get one from the net?

or

is there a downloadable burning program that i can use to burn an MP3 disc without any kind of file limit on it?

the emergency is, i have to do this before i fly out tomorrow... so any help would be greatly appreciated!!!!!!

thanks.
