3rd Monitor stopped working after driver "update"

I have 2 AMD Radeon HD 7800's hooked up in Crossfire with 3 Monitors (DVI and HDMI on the top 'main' card, and another HDMI on the bottom card).  Everything worked fine for 2+ years.


I downloaded a game (PUBG) the other day and they told me there was a known issue and to update my drivers.  I did.  The 3rd monitor stopped working.


From the device manager, I rolled back to the previous version of the drivers and the 3rd monitor started working again.


I shutdown the computer later in the night and then when I restarted it the next day, not only did the 3rd monitor not work but the "roll back driver" option was no longer available.


I bought an "Active Mini Displayport to HDMI" and plugged the HDMI cord into that and then the adapter into all the miniDP slots on both cards, but still won't work. 


This has been going on for over a week now and I've finally exhausted googling and forums and can't find an answer.  Can anyone help advise me on what to do?


Thank you in advance for any help,
