Hello everyone.  
I’m a student and I’m new to Linux. I want to use AMPL to solve my formulas for my project. I downloaded the Community Edition and the AMPL C++ API. I extracted the tar file in Home/Downloads and ran ./ampl. In the second step (step 2), the site gave me a unique license to activate my software. I ran ./ampl in this directory and input the unique ID as instructed.

My problem is that every 5 minutes, AMPL shows the following message. When I run AMPL with sudo in its directory, everything is fixed (sudo ./ampl).

What is the problem and how can I fix it?

License file ./ampl.lic:  
Short term lease expired. Please make sure your internet connection is working in order to renew the license.  
Current directory = “/home/\*/Downloads/ampl.linux-intel64”.  
Today = \*; found license file “./ampl.lic”:
