Model Import Problem: TFT Models?!

Ok. I don't have TFT yet. I'm poor. So, to set things straight now, I'm still using the ROC World Editor. So, I went to the 'models' section of the site and got the 'War3_betapack_1.0'. Inside, among others, you'll find:

'Buildings\Other\MarketPlace\MarketPlace.mdx'
'Buildings\Other\MarketPlace\MarketPlace.blp'

I put these in my WarCraft III directory. When I open the World Editor, and I type the path in to a model file, the building appears and I can view it right there in the World Editor.

However, when I try to save, the editor tells me "Your map is now an expansion map, do you want to save?"

I am now confused. I thought the models in the pack were WarCraft III: Reign of Chaos BETA models. How can I circumvent this problem OR should I even attempt to get around this?

A little help... please?

EDIT: i wrote somthing stupid my bad
That is wierd.... Maybe its the new patch or something that made your thing screwy

Were did you get your beta pack? here or at another wesite and can you post it?
