Cannot add addon

I am running Version 1.5 build 990.

I downloaded the addon for sounds. I tried to follow the directions in the settings ->events screen, but there is no such item as Start -> Smart FTP -> Add or Remove Smart FTP Components.

How can I get the sounds to work? If I simply extract them from the .cab file, there are sounds that I want to use for which there are no entries in the events screen.

Just heard from tech support that unpacking the .cab file and adding the sounds manually is the way to go.

In other words, disregard previous message

Thanks to all who did respond or would have responded.
