A LoadMovie Issue

I have a main swf that loads another external swf to a blank MC. The main swf is loading great. The external, on the other hand, isn’t.

If I check the swf files on the server, they are both working fine.

Main SWF - It is loading the external swf.

If I check the Testing Site , it isn’t loading the external swf.

I don’t understand what the issue is. Can someone guide me in the right direction? Thanks.
