huhu!
I have the NEWEST version of BLENDER with correct installed PYTHON in it!
THe PROOF:



The next proof: i downloaded the MDL7 EXPORTER TO EXPORT Models from Blender to the bad programm called WED or MED!
The first big problem: i cant export it because i get an error! Why do i get the error? I put the script into scripts folder of blender? I DOWNLOADED the damn MDL7 Exporter 4 Times from 3 different sites and NOTHING solved it!
I dont know how the future will look like

I hope that someone can help me to solve this problem!
