BBC Listen again function (Real Player)

I used to ( a week ago) be able to use listen again and suddenly I
can't.(this has happened before, though I don't know why it happened then,
I'm sure its happened to others)

I'm listening to Radio Scotland - couldn't find a news group sorry.

Listen live works fine - a seperate realplayer window launches, but listen
again won't work!

Any suggestions very much appreciated as I'm missing Iain Andersons progs!
