maximum polygons?

Hi. I have a pretty complex model I've been working on, and when I try to export it from gmax (1.2) to .mdl, I get an error that mdlexporter couldn't be found or sumthin of that nature. I have the .dle (I don't have progs open and I'm tired, so bare w/ me) and mdlmaker.exe or whatever in the root dir for gmax, and in the plugins folder, and in the flightsim folder. The last error msg says that the export failed. It actually does create a .mdl file and a .log file. The log shows the exporter processing the polygons, but then at the bottom says the units are metric, and something like 1024.00-1 and then error, error. I can supply logs if someone can help. I'm curious on the max number of polys you can have in your model. This one is pretty big, and I didn't exactly keep them down when I started modeling it. I can start over w/ fewer polys but would rather not. Also, the mesh is not closed, and is not complete. I do have open edge errors. Do you have to have a closed mesh bubble, or can it be open. Any help would be appreicated. Please feel free to email me p-light@earthlink.net below is image
