anyone know how to "reconnect" tRev with Revolution?

[Josh Mellicker]

tRev was working, but now the "agents" connecting tRev with Revolution  
have apparently gone rogue.

recipe:

launch tRev
tRev launches Rev automatically
open stack from within Rev
edit script of something
Rev's default editor appears
tRev just sits there, empty.

Snow Leopard. Rev 4.0.0 dp-4

Has anyone run into this or know how to "reconnect" tRev with  
Revolution?
