Hi all,
I have been unable to access ArcGIS Pro for 3 days now because every time I attempt to log on to the desktop, I receive the error message below. I have tried to follow the support pages, but I can't even get to the home page on arcgis to switch into online mode from my computer, and I've tried to configure my license, but since it's not considered registered to this device, as per the error, I don't believe it's helping. I've tried to contact customer support but I really need to figure this out urgently, as I require ArcGIS Pro for work.

Any help is greatly appreciated, thanks!
