I get that error no matter what version of Spelunky I boot.
I always have, but usually I'll just try again or open two at a time and it will work.
But recently, no matter how many times I try it's success percentage is probably around 1/20 times of trying to boot.
This error may have been reported before, but I don't check this area very often, so I am unaware of any previous threads about this error being encountered.
Is there any way to fix it? Or must I just live with it? -.-
