Skyfire MapFollow

I have downloaded, redownloded, saved, etc., all of the maps from Mapfiend. For some reason, I can never get Skyfire to work (or M Seru for that matter). Any advice is appreciated.

Have you checked the name of the file? I looked at the mapfiend site and it seems that there are two maps for marus seru and they both have different names. I'd compare the file names to the rest of your maps and see if you can simply rename it. If not, try downloading the map that you didn't download and see if that's any better.
Hope that gives you some help.
