Hey Dan,
Just checked the I'mSick.net forum, and someone mentioned some problems with Orbiter that fixed themselves once
he re-downloaded the new version. I just did a check of all the download mirrors and I noticed that yours is slightly
off in terms of the byte size for the three files. Accident? French use of metric computer units? Intentional
sabotage?
I think I had the same problem too, and I had originally downloaded from your mirror site, so I'm
wondering if there's a problem there.
