Apparently, the K45 file is kinda' defective. You can delete the saved game at your User Files directory, and download another saved game. I tried that one on a computer, and it worked for me...
Oh, I don't think its defective.. I think its cause maybe my main.scm or something is different. I'll try to think of something but thanks for your help . If what I am gonna do doesn't work I'll follow your advice.
