Hi John-Thomas,
This is Mike from Brightside Church.  Your problem is that hdmi doesn't travel over 50 feet without an amplifier.  We tried to do the same thing with the same results.  
What we ended up doing was to convert the signal with a hdmi to cat5 adapter  and then back again at the projector.
