Suffix Textures Fail Name and Directory Mess Up

When attempting to import _suffix textures (normal maps with _nm as an edited suffix) I find that instead of them importing correctly, they get strangely mangled in filename and destination.

So, MyImage1_nm going to scene/myscene/textures directory ends up as:-
TexturesMyImage1_nm in scene/myscene directory

Spot the obvious error.

If I manually import the file into the correct directory with the correct name I get a JIT error on export as *.mis file and no material.cs.

Note: I've got my scene files in PL in Program Files directory, but I don't think this has anything to do with UAE.

Apart from that, new version of PL very nice, preview quite cool.
