well I got the same problem, the mediaplayer (windows, flash) appears but it doesn't work. The code and the link should be okay. Tried all the different settings to see if I did something wrong, even tried several different upload folders on my server. I use WP ver. 2.2
This is an example of the code I am using:
[coolplayer width="320" height="240" autoplay="false" loop="true" charset="utf-8" download="false" mediatype=".wmv"] web 2.0 (<--this is a link to the file, http://www.yoursite.**/etc.etc....) [/coolplayer]
I tried different width/height settings didn't work. The Fast Tag button doesn't insert a mediatype, so in this example I tried to insert the filetype .wmv, but that didn't help either. Somebody got this plugin working?
