ML Up-to-Date Download Error in App Store

[benpop]

I have just acquired Mountain Lion in the App Store via the Up-To-Date Program. However some time during the download the connection dropped and ever since mountain lion is listed in the purchase history under other purchases with the error message "an error occured" and the grey button (where it usually says install or download) has no text and clicking on it won't do anything.

Can anyone help?

Going to sound daft but have you tried killing the app store app and restarting it?
