Flv fullscreen problem with classes

Hi,

I’m working on a project where they want me to add a fullscreen button to an flv player. I get the feeling that the flv is somehow being loaded from a server on the web somewhere. When I try to test the movie I get errors for the pieces of the flv player. They say stuff like:

Symbol=Time Display, layer=Delimiter, frame=1, Line1 The class or interface 'com.liken.TimeDisplay could not be loaded

Can anyone explain to me what this means so I can try to fix it?
