Egress IP Error

I just bought Adobe Premiere Pro but when I trying to open product gives me "Sorry, your sign-in attemp doesn't match the Egress IPs of the profiles that this machine is assigned to. Please contact your IT administrator." 

I'm an individual user but back in the days (I think 2 years ago) I was a student at college, I use Adobe Cloud and Premiere Pro thanks to school and I think that problem comes there but I don't have an idea how to solve it. Thanks.
