Failed To Initialize Drawing Surfaces *Solved*

[Gazoinks]

Alright, I signed up so I could ask this:

I downloaded Spelunky a couple of days ago and have been enjoying.  Today, however, when I tried to play it, I got the error: "Failed to initialize drawing surfaces.  Please check that your graphics card meets the minimum requirements and that your drivers are up to date.  If your graphics card has little memory, try switching to a lower resolution."

The game had been working before today so I know my graphics card supports it.  I have tried redownloading it, but the problem still persisted.

Thanks to anyone who can help me.
Never mind.  It mysteriously started working again.  Sorry 'bout the unneeded post, deletion is welcome.

Gaz, you can delete the post yourself if you like, on the bottom left. But if you can figure out what happened it might help someone else in the future.
