error -7112

hi everyone!

I hope you could help me with my prob. i've been using the H20 and all of a sudden when i was ready to shoot after the connecting bar has fully shown there's this clicking sound that activates in the H20 then the green ready lamp suddenly blinks without me depressing the shutter. then C1Pro would prompt me of the sync cable being not connected properly. i have changed camera body, lens, sync cable, firewire and even computer. the problem still persists. Ulf i hope you're listening........
