After the game loads to the "Press Any Key" screen, pressing a key results in an empty white dialog box with only an exit control visible. After dismissing the dialog the red cube spins forever and my characters never load.

The white dialog appears to also contain a white web page control as right clicking on it reveals a context menu with "Show Source" as an option. Showing the source reveals an HTML document block that contains totally empty Head and Body elements and absolutely nothing more. No text elements at all.

Deleting local data and re-installing didn't seem to help. I updated both the GPU driver and Windows. No change in symptoms there either.
