help Problem with UE2 textures

[911reg]

Hello there, my problem is that whenever i try to click "use" when making a texture, UE2 suddenly stops working and won't work 'til i force it to shut down. I tried every single compatibility, i tried to open it as an admin, etc. but nothing worked. If you know about any kind of solution i'd be very grateful!

that usually happens if you try and put a shader in diffuse

Yup, it does. The problem is, that's exactly what i need to do, but UE2 crashes right when i try to use that button.

what is your goal exactly? have you tried combiner?

I'm trying to edit some weapons/armors/mobs' textures, etc. Things like that. I don't need 100% to use shaders, but still it would be nice being able to use it.. About "combiner", could you give me some info about it? i can't find anything on google

pd: thanks for the fast answers <3
