Problems loading classes CS4

why, why , why? CS4 issues

I have a movie that reads class files located in folder called ‘src’ and has been working once I changed the path to absolute. for some reason now my movie has decided not to work.

this is how I create the path:

Go to porperties and click ‘Edit’ then clicking the AS3 ‘settings’. I then go to the ‘Source path’ tab and click ‘browse folder’ icon to the folder of the classes.
having done all this my movie still does not work. does any one have any thoughts on why it is happening now?

help please!!!:crazy:
