Game crashes after starting, leaves a smoke square

[CaptainMaim]

I don't know why but my game's crashing on startup and after it does the map it just gives me a black screen and the lower left corner has a gray smoky tile. And nothing else happens..

Also boost::filesystem::path: invalid name "060312-!!Battle_Holms!!_v1-0.70b2.sdf" in path: "demo/060312-!!Battle_Holms!!_v1-0.70b2.sdf"
----------------------------
Another errors include "Unknown Key: 0xa7"... And also "/"

I've also gotten a:

Using ARB_fragment_program_shadow
Using EXT_framebuffer_object
Spring has crashed
