Here's the plugin: http://coolplayer.sourceforge.net/?plugins#wmaplu (sorry, my HTML skill is somewhat lacking...)
I installed it to play music on my flash drive, but, Coolplayer doesn't natively support WMA, and VLC crashes when I try to edit a playlist. Basically, I'm just trying to get it to install the plugin properly, and play my music.
I'm open to any ways (using PortableApps software, or otherwise) of converting music to .ogg format. I just tried VLC, and it froze my computer temporarily.
