Ok, hope you'll find the energy soon, SP1 is really an improvement.
As I can't check for errors in my own Black Widows, I DL jorams Central Vermont GP9 and as I remember a quick fix. I got "could not load texture....." as for error. If you open in Explorer and go into the "body folder" you'll find a "main texture.texture" file refering to a .tga file that isn't present. Remove that text-file, close and commit, then it should be a go. Just make sure the .txt file you're removing doesn't have an actual texture file in the directory.
