Help! Firefox can't find "startup.txt"

Yesterday morning i was happily working on a new Choicescript game.
Today, firefox says it can’t find “startup.txt”.

The files are there.

So i went back and tried to run my old CS games, they don’t work either. Same error, but the files are all still there.firefox%20error

Please help!
