Having a bit of trouble attaching something

For some reason I can't attach a certain map... It is well within the size limit. Unless 3.1 megs is bigger 5.0 megs, something is really screwy.
Sorry about the tone.. Just a little flustered with the fact that I was going at it for about 10 times with a slow loading process in each try. I tried it with using an existing link, and the file directly. Should I just email?

Quite a few people have this problem, it has somthing to do with windows. For now, just link to the map offsite and I can attach it for you.

Problem solved. Thanks

Probably because you don't link to the actual file, but to a php file that returns the file to the user. That does not work here, you should try using the real link.
