since I couldn't find any answers through google I decided to register here.

I'm a beginner to modelling so it could be just a minor thing that I simply can't see.
I use 3dsmax 7 with MDT 2.75 @Win7 64bit.
For the start I use this tutorial but I'm stuck already. When I export the model it just doesn't create a .sm file but there is no error message either so I don't know what I do wrong.
1. I pick the model that I want to export and use the options from the tutorial. Look at the header of the export tool, it says Ver 2.52, is that the right one?

2. I choose to overwrite the existing .sm file (as suggested in the tutorial).

3. Somehow it didn't save because it's still the old file (see date). The old .rs file was overwritten though.

I hope that I'm just dumb and made a nooby mistake.

Thanks all!
