Ubuntu 9.04 and BBC Iplayer

[Andrew]

I'm trying to run BBC Iplayer with Ubuntu 9.04 and keep being told to
upgrade my flash to 9.0.115 or higher. However, when I try to download
and install the latest version from the Adobe website I get the message
that the Adobe flash plugin is already installed - I've also tried it
from the command line using 'apt-get update' and 'apt-get install
adobe-flashplugin' but to no avail - it simply will not allow me to use
the iplayer. Has anybody else found a solution to this frustrating
problem please?
