both files are the same, only the extension are changed. basically, they are softcam.key files renamed as either .ke2 or.cod for conformity with the loader being used. try using the stb repair procedure as posted at al7bar-soft1.com and reload with the latest .ke2 file available. i know fortecstars are kinda very slow on the upgrading process, so be patient when repairing. good luck!
btw, i'm not mach1 obviously
