In your last screenshot of the Inkscape canvas, it looks like something is selected. Have you scrolled around to see if anything is showing, anywhere, at all? I mean, Inkscape seems to know what size it is. If it knows what size it is, it must have found it.....
"incorrect reference" I wonder what it means by "reference"?? Is Drive F connected to the computer?
"incorrect reference" sounds like Inkscape can't find it. But it's at least found what size it is. If you follow the file path which is showing in the status bar, do you see the BMP image? Can you open it with an image viewer?
I suppose it's possible version 0.46 can't display BMP images, but that doesn't really seem very logical.
I'm fairly well stumped with the BMP problem, at least for now. Can you share the BMP file? Could it be corrupt, or something like that?
I found some brief info in the manual about BMP files, and it says that Inkscape will display them. There's a comment there which gives me the idea of trying to embed the BMP. So while it's selected, do Extensions menu > Images > Embed Images. Apparently that will convert it to a PNG. I don't know if that would work, but it can't hurt to try.Nevermind, I don't think that extension was available in 0.46. But if you can find any kind of option for embedding the BMP, it won't hurt to try it.

Regarding the problem with DXF, I'm probably not the best person to ask. I found these 2 older extensions - so old that it's not surprising that they don't work in the current version of Inkscape. The traceback error you shared sounds like it might come from one of these (although I don't really understand much about what the error means - I just recognize the file name).

http://tim.cexx.org/?p=590With the current version of Inkscape, DXF can be saved natively, without need for an extension. When you say you need a "better output" exactly what do you mean by that? I know there are different types of DXF, and I know some people use other programs to get the right type.
I don't know if any of these would help, but these are all the DXF export extensions that I know about. I don't know if any of them might work better, with the current version of Inkscape. Or maybe you have already researched this, and you've already tried them?? But just in case:
