activation/reactivation on Mac update

I commented on an earlier thread on difficulty with 15.3 and activation/deactivation.  I want to add some more details.

From my previous post -

"I have a related problem. Upon launch, new version says license code could not be verified by server and gave me a choice to quit or deactivate.  When I click deactivate I get a screen that says this version has been activated when I click deactivate it says it could not deactivate the software on the server.

So, sounds like it might be a permissions issue communicating with captureone.

However, if I install and tell it to keep both copies, the new one opens fine, authenticates fine, but is a blank copy, no styles, process recipes, etc.  This seems to argue against the communication permission idea."

-------------  New info and workaround---------------

In the first screen that comes up, I notice that there is no activation history, even though the screen indicates that this version is activiated.  I have tried deactivating at my C1 account and think the upshot is that I have the local file and the C1 file out-of-sync, likely need C1 help. 

HOWEVER

If I turn off wifi and am completely discounted from the web, C1 starts up without issue. I can import images and work on them. I have not checked for bugs that others have reported. 

FURTHERMORE

Once I am running offline I can go back online and still work with C1.  I can also check license, try to deactivate - no joy - but, the program does not crash. 

WORKAROUND

For me, the workaround is to go offline, start C1, then go back online.  

I hope this might work for others.
