Hi - I upgraded to 1.05a last week. Now none of
my RealPlayer music will play on the device, despite
having been bought.

The 1.05a upgrade was done on the same machine
where all the RealPlayer music was downloaded from
weeks/months before and had been regularly played.

When I try to play a song, RealPlayer says:

You do not have the rights to play this protected

To fix this, connect to the PC where the owner
of this content is registered.

Is there anything I can do to get my music back?
There are hundreds of songs there and I don't want
to re-buy it for chrissakes.
