CrossfireX option greyed out in CCC

I had 2 x Asus HD7770 working in CrossfireX for a long time without any issues with driver AMD_VGADriver_Win7_Win8_Win8_1_VER13_152.

After an update to Crimson 16 series, the option in CCC to enable/disable CrossfireX is greyed out and there is a message saying:

"The internal bridge interconnects are not properly connected. Both bridge interconnects must be connected."

Uninstalling the driver, cleaning with DDD in safe mode and reinstal of previous driver won't solve the issue;

Inverting and reseating the cards won't solve the issue;

Fresh install of OS in another disk with previous driver 13.152 won't solve the issue - they still don't work.

Both cards work perfectly as single graphics adapter, so it almost appears that the 16 series Crimson driver changed something inside the cards itself...

Any ideas on how to get CrossfireX working again?
