tool is making up errors

Ok, so I have my map and in my map I have a box. Just a box. And then I target welded the two top verts to the bottom ones to make a primitive ramp. Now, tool thinks the whole thing was an open edge. I've had this before and usually it goes away if you just recreate the faces. Now, this time I did, and now only SOME of the edges were open. I continued ignoring the open edges while I debugged the rest of my map. Throughout the debugging process the edges that are "open" continually change. Sometimes it's on the left, sometimes the right, sometimes the top, etc etc etc. The next wierd thing is that I duplicated it and moved it to the other side of my map (which is symmetrical) Now, this other ramp (which I cloned from the errored one) has NO errors at all.
I don't get what the fuck is going on here.

And the ramps are all triangulated and are editable mesh
I'm using Max 9 and Bluestreak to export. Any help would be really appreciated

EDIT:
I'd also like some help with portals
Basically, I have portals working completely fine on the left side of my map, then I mirrored the portals to the other side, lined them up EXACTLY (believe me I checked) and now all the portals on the left side work and only some on the right side :\
I also get crap like this:

Where, in max my portals are perfectly aligned, but in sapien they look like that.

Are you using bluestreak or blitz.

Bluestreak

Thats why, bluestreak sucks. Use blitz

well your screwed then, bluestreak for the most part fuckes up exported models. Although you can try triangulating your model before exporting.

Seriously, please read the OP
I already triangulated the models :\
but thanks anyways
I guess I'll have to "acquire" max 8 from somewhere...

Enjoy 30 days of 3ds Max 8, legally and free of charge.

Assuming you haven't already. (This is the 30-day trial as it would be normally downloaded from Autodesk, but they don't provide the old ones. Check under that directory for older versions. Further warning: Max 8 will NOT open your model, export is as a 3ds and reimport it into Max 8)

I already have enjoyed 30 days of max 8 :(
Thanks anyways though

Then pick an earlier version, they should all work with Blitzkrieg.
Max 6 is good stuff. Ahh... such good times...

Aight thanks man, downloading :)
