Just create a simple plane model, save it as .3ds and load it. Then see at which point the texture coordinates get messed up. It should be 0/0, 0/1, 1/1 etc. when you load it.
If you want to save yourself a lot of time, then forget about 3ds, its lacking things in too many ways. Try .obj for a simple format that also supports bigger meshes. Its also very easy to create your own loader for it.
