I have been using this program for some time (DTX.bmp) without problems. However I have downloaded the newer version from the website and now it will not let me use FSDS with any models containing textures without causing an error.
If I try to add an existing texture to a new model, when I try and seslct the texture it does not show up.
I have had the same problem some time ago when I loaded this program onto my laptop (WinXP pro) and as a result have not used it for texturing, however I sem to remember that I had to delete all textures first!

Any ideas as to how I can get my textures back would be helpful.

mwgfx update for FSDS2

What has happened is that the installation of the new DXTBmp has installed a newer set of dlls to the system and these are not compatible with FSDS1/2. The update places a compatible version into the FSDS program folder so it will use that instead.
I think Louis modified the FSDS3 code so that it will run with any version of mwgfx but the previous versions required a specific mwgfx.dll
