Q: No button text on Lion download

Here is a rough transcription of how I got into this state:

* Purchased Lion with a redeem code from my developer account

* Download started and progressed to approximately 3.2GB

* I closed my Macbook Pro and switched to another WiFi connection later

* I somehow lost all my download data, and the download was stuck in "Waiting..." mode

* I clicked the X, and the OS X Lion download reappeared in the Other Purchases section

* I believe the download started and progressed for a while until i quit the App Store application

* I reopened it, and I'm left with this state

This all occurred when I was running 10.6.7.  I updated to 10.6.8 to see if it would fix the problem, but it remains as shown.  I do have the Lion download icon in my dock, and it is making progress.  I'm not sure how the Lion upgrade occurs, but I'm afraid I'm going to be stuck in this text-less button state even after it completes.  Has anyone enountered this before, or know of any fixes?
