Fixed SÖLDNER Demo

As noted on Planet Soldner, the multiplayer SÖLDNER: Secret Wars demo released earlier was 4F (thanks Tiscali Games). Word on how to tell the proper version from the corrupt on is: "Make sure the filename is soldnerbeta_demo.exe (Filesize: 224,141,974), this is the updated file. The old, corrupt file is called soldnerbetademo.exe." The updated version of the demo that has been confirmed as working can be found on 3D Gamers, ActionTrip, Computer Games Online, FilePlanet (registration required), Filerush (torrent), FileShack (registration required), Gamer's Hell, and Worthplaying.
