I downloaded an Eagle library and placed it into the library folder of my Eagle 7.7.0 folder on C Drive.
I opened a new schematic, went to the Library > Use in the menu and selected this new library. It was available there but when I go to add it to the schematic it is not available.
What am I missing here please, as I do this all the time with new libraries that I make or modify and do not usually have any problems. Thanks.
