Dell Streak download issues

Now my Dell Streak will not download at all from the Market (app store). It's incredibly frustrating. And not at all uncommon, a Google search gives nearly 22,000 results!

I've rebooted of course, no joy. And so far I've not found any help.

It's a pity, for otherwise this five-inch device is not a bad pocket-sized ereader.

Update:
Hurrah! I found the solution here. (It's not "options" though, it's "settings", in the menu from the home page.)
But I have to say that it's a really poor show that an update to the Market app will block downloading...

I even found an app (Hard Copy) which will let me read my Instapaper articles on the Dell, kewl. (Although it seems to have no options for changing text size, quite a disadvantage which I'm inquiring about.)
