I've been sporadically but quite often been getting this message when it should be downloading and installing apps grom the market.
When the Tab is in this state it seems that those apps are unable to download until I cycle the WiFi (switching to flight mode and back) and retry.
Once it is working it seems to work fine again, but it can be a pain when it happens. (This caused me to buy an app twice at one time... only realizing this once I saw the emails later)
I have tried it on 3 different wifi networks on which all works on my Droid X, and it has happened about on 30% of the times I installed apps. (I have rebooted a few times in between too)
