I spent all day literally downloading several sounds (century keys, strings,etc...). I have a very slow connection.

Anyway the 1st one I tried to install was Century Keys and it doesn't show with the other instruments. I found the file folder with all the other sounds (Celtic Harp, Vita 2, etc...) and the Century Keys folder is there with them. I initially thought I may have screwed up the download path so I reset everything to factory settings and tried again. Still no luck. And there is no error message.  Can someone please help? I am very new to this type of software. Thank you
