Hy guys! I am new to this forum/engine; but not in programming and modeling

I have started to program a FPS game in VB 6; I have made the appropriate folders (mesh, textures, TV3D dll.s), and I have these strange bugs:
When I try to add the weapon (to me) it doesn't load it- all paths for folders are correct;
When I try to compile the exe the result is a big blue screen with the TV3D logo on the right and no mesh (it does not seeing the terrain)
Strange is that when I try to run the program in the TV3D directory (C:\Program Files\...\TV3D) is working fine...
Why is not working in my folder??? Why is not loading the textures, mesh??? Why I can't share my WIP with my friends???
Excuse my bad English!
