Can't access matched library from another machine...or same machine

I processed almost 10,000 songs on a MacBook, the music files reside on an external drive. I then autherized iTunes Match on my PC laptop, but after it does the initial Match process (zero songs from this machine), I can't access any of the iCloud tunes. Then I tried the MacBook this time disconnected from the external, and it tells me 6912 songs are now available from my iOS 5 device. But all I want is to access all the tunes from my computers (I'll worry about iOS devices later).

On the PC, iTunes view menu is largely grayed out, so I can't check view options. and I haven't let it upload the tunes that didn't match yet, as that will take some time. But I am disappointed I got this far and apparently can't access my iCloud matched tunes from the desktop.
