It's possible that the emulator screwed you on that game when those files got deleted and recovered. This thread might give you some insight as well, as unless you closed and ran it more than once yesterday before it stopped working, you could have a similar problem to those guys. This could also just be a problem with your version, that dev build is from some time ago, downloading the latest version is a good first step. If that doesn't work, calculate the MD5 checksum from the game properties "Info" tab and post it here, could also be a bad dump.
