Egress IP Problem

I purchased Adobe Creative Cloud Pro, and the installation went smoothly. 
However, when I try to launch an application, 
I get the message: "The login attempt does not match the egress IPs of the profile assigned to 
this computer. Contact your IT administrator."

My computer is running Windows 10.

I intend to use the programs for personal purposes and am NOT part of a company or team.

I only installed Adobe Creative Cloud Pro on my personal PC.

Several years ago, I had Adobe Creative Cloud Pro installed on my PC. 
It was provided by the school, but I uninstalled everything using Creative Cloud Uninstaller.

I would be very grateful for any solutions or tips.
