Problems with Slacker Radio on Fluid

I am new to Fluid and was unable to find any support forum on their site, so I will try out my problem here.

Set up Fluid apps for Slacker Radio and for Pandora. The Pandora one works fine. The Slacker one does not work. The site loads, but the middle area where the music play is is just black. If you click in that area, there is text you can actually select, which is a really long error message.

I have gone through the settings on Fluid and I am unable to find anything that fixes this. Does anyone else use Fluid for Slacker Radio? Anyone experienced any problems? Slacker works fine through other mac browsers.

 

In case anyone stumbles upon this issue in the future, I was able to get it to load by choosing User Agent > Safari 3.2.1 Mac under the menu bar for "Slacker" once Fluid was open. This loaded it up. So I guess it is a problem with whatever user agent it was choosing by default not liking the way Slacker was coded. Problem solved.
