Load From Remote sources, EPPlus 4.0.3

Mar 10, 2015 at 8:14 PM
I have downloaded the EPPlus 4.0.3 to create an Excel fil, but I, who is a beginner :- ) get the warning Loadfromremotesources......, then I have two questions
1) What do I do to avoid the warning ? and
2) What is my program trying to load from a remote source ? ;-)
