Gray Box - No Editing View

[Jaanuman]

I need a little help from you TF experts out there. My main window is not showing anything other than a Gray box, which makes it fairly difficult to edit something. My overview window is just fine, and when I click the gray box area with any of the brushes, the overview window does show action being made on the terrain, I am just not able to see it in the main window.

Help!

And please can you post a screen shot ?

I got it to work on my laptop. I think my desktop has a problem with its Direct X. Thanks though.
