Here's the situation....

I had a fully updated install of CODMW2 with stimulus package.
About a year ago my PC corrupted, I reinstalled CODMW2 using my install disks but didn't get around to fully updating again.
Just after this I moved to a house (reluctantly) without a broadband (ADSL) connection. Without broadband I stopped playing CODMW2.
Recently I moved again and now have broadband.
I went to update and play COD (current version on PC 1.2.208). The 'download content' button has a bright green 'new' next to it. I clicked 'download content' and nothing happens.
When I went thru Steam to download this new content there's nothing available.
What gives?
