Problem with 3ds max 8?

Hi, I have problem... I have started modding while ago, and now I wanted to start moddeling. So I bought 3ds max8, I try to install W3arttools, and what? Error... "this plugin isnt prepared for this version of 3ds max" or something like that. So what can I do now? Is there a version of art tools that will work with 3ds max 8? Or any other way to import *.mdl files into 3ds max? I dont want to buy new program... I think its not ever possible to buy 3ds max 4/5 right know pls answer

Edit: I know this is wrong forum for this question, but I dont want make another thread... im working with my friend on some project, and for example I make map, and he make heroes... is it possible to transfer heroe from his map to mine? Some kind of merge?

1. I think Art Tools only works with 3ds max 4/5.
2. You can export the unit and ability from one map to another, but when exported, everything would be overwritten (object data) in the map it's being imported into.

Ty for help but... where do I find options for import/export object data?
Edit: Found it. SO i still w8 for answer how to import *mdl files to 3ds max 8 :(
