Problem with PC & new Mix unit.

[KeyplayerG]

Long story short: I did a remodel in my studio that was supposed to take 2 weeks. We are finishing at week 12!!!! :x The PC has been off almost the entire time. I just fired it up to test the new displays a week ago and made a scratch recording on Thursday. Windows 10 did some kind of critical upgrade overnight and as of yesterday I have several problems.

1) Me elicense has deactivated one of my programs, BUT WON'T TELL ME WHICH ONE! It's just giving me a serial number to track down. The Nuendo license and my EWQL license all seem to be working fine. But when I launch Nuendo, it tells me that I don't have enough permissions to work properly.

2) I can't double click on ANYTHING to get it to open. I have to right click on everything too open the menu to tell it to open (very annoying!),

3) System Restore won't offer me a date before the, so called, critical Win-10 update that took place Thursday night. So, no option of normal recovery there.

4) I've gone from a 12 fader Artist Series setup to a 20 fader setup by adding a second Mix. But I can only get any 3 of the 4 devices to work. So, I can get both Mix & Control to work, but not the Transport or I can get the Transport to work with a single Mix & Control. I have purchased a new TP Link 16 port network switch, hoping that will solve the problem. But, right now, I'm more concerned about the 1st three problems mentioned.

5) Has anybody here ever had to deal with something like this? How do I get my PC back to normal? Thanks!

I'm on Eucon 3.6, which worked fine until this latest Win-10 OS update. ADK thinks the issue of the loss of the double click function may be traced back to that, since we turned the apps off and reinstated them one by one. When we turned Eucon back on, I lost the double click function again. Hopefully, updating to 3.6.1 will solve the issue.

Anybody here on a PC with the latest iteration of Win-10 having troubles with Eucon 3.6?

The results are in. Eucon 3.6 is NOT compatible with the latest version of Win-10. I had to uninstall my eLicense and update to the latest version to get that back to normal. Then I had to do the same with Eucon. I've updated to 3.6.1 & the PC seems to be back to normal as well. Just so you know.
