@edsel - I scanned 13E last night just for free-to-air channels and got almost 1,000. Once you eliminate a configuration (or cabling issue) as per @abu's posts, I think you need to verify that your dish is pointing correctly at 13E. My location is in Ireland at 6W, so it may be that you can't receive all beams in Sweden, perhaps?
EDIT - I checked the beam coverage for 13E in Lyngsat and Sweden is well within the pattern, so you should be receiving almost the same signal as me.
