Arduino software does not recognize library

I downloaded a library called "Password". No matter what I do on Windows 8, the software refuses to acknowledge this library is there. Every time I try to compile one of the examples, it gives the error "'Password' does not name a type," even though the example is being opened through the "Examples" option under file. Ironically, I was able to get this library to be recognized on my Mac Arduino software.

The only other issue of which I can think is that I tried to open the Password.h, and Windows wanted a file type to associate it. Now it is attached to Notepad permanently since WIndows 8 seems to have no way to disassociate file types. I have tried several ways suggested by others on this matter.

Any ideas?

Have you restarted the IDE?

And, where did you put this library?

As I was looking to write the correct path, I figured it out. It was under /Documents/Arduino/libraries/Password/Password. Somehow, it created a double sub-directory. I guess the software didn't like the .h file an extra level deep. I moved it, and it was fine.

Thanks!
