Help Umodel problem

[Vertigone]

Hey, i wanted to ask about 2 problems

1) when i try to import staticmeshes or textures using .bat script "umodel -export -all <filename>" it instantly closes the window and no textures/meshes are imported. i tried following the tutorial with adding effects to the npc and i'm having problems in that part

2) my umodel often says that the file is probably read-only, is there something i can do with that? i checked the file etc.

thanks for help in advance

if you using latest umodel is not necessary anymore -export -all, just export is fine or umodel in the folder are located files.
