Just a thought but you might try surfing while the upload is in progress and if that does not work. I would try and reduce its size if over 1mg since
some providers limit your upload amounts.
pshaw! Don't feel silly. It was good! (what I heard of it anyway. )
Open Audacity
Project - Import Audio (select existing PODcast)
File - Preferences
Change bit rate to 32
Then save (export to mp3)
Check the size, it should be a lot smaller.
