Rachel,
Welcome to BibleSupport. Glad you're having a good experience.
When you click the Reference Library icon, you should be able to select Evans from the drop down list of files, like this:.
If not, click Options > Resources. Find the field called "Location" at the bottom of that screen and make a note of that folder. This folder tells e-Sword where to find resources. Copy Evans to that folder. You may then have to re-start e-Sword.
thank you, it did help to have it downloaded. What patience you must have dealing with novices like me. Over and Over.
I'll be back when i have tried out a few of these fabulous resources!
