I believe 1.18.00n is the initial version you get with the download from the PlayOnline website, or at least was still not long ago when I last tested it.

It does look a bit odd that it has the 'Front Mission Online' title there too, but perhaps that's on the US version only and not the EU one I'm looking at right now.

If something like 'dgvoodoo' helps, I suppose it's a problem specific to certain graphics card drivers. Which one is being used here?
