[flexcoders] Problem when trying to use RSL Cache

[boy_trike]

I am using FB 3.  in Project / Build I select frame Linkage RSL.  The swf is 
smaller (GREAT) but 
when I attempt to run it, I get (mx.core.Application not found).  I copied over 
both of the 
framework libraries (the SWF and SWZ) to the same folder as my SWF.

What am I doing wrong

thanks
