WP Audio polayer not finding audio file(s) please help.

Have installed the latest beta of [Plugin: Audio Player] Version 2.0 ny Martina Laine. Since that thread is closed I stared a new one to ask about the placement of my audio files files.

I entered the exact file location starting with https:// my domain name etc in the custom setup field. BUt whether I type in the entire file url or just the name – when I try use the player it says “File not Found”

Can some one help me troubleshoot this please?

This is all new to me. thank you
