Hi TickyTacky,
If you have installed TS2009 in the last few days, that is around Dec.26 or 27 and after, you will not be able to download items as there is a problem with either the Download Station or Planet Auran.
You are not the only one affected. This has been reported to Auran and the problem will be investigated on Monday.
Until then, patience.
Cheers
Gilles
