Hi Andras - MoI writes out an Adobe Illustrator version 8 AI file.

It seems that for some reason Inkscape does not support that kind of AI file, they only seem to support version 9 or higher which is a fairly different kind of file which is basically the same as PDF.

One good way to do the conversion from MoI into Inkscape is to use this inexpensive ($39) drawing program called Mayura Draw (http://www.mayura.com/) - it can read in the version of AI file that MoI exports, and can then save out an SVG file which Inkscape can read.

That would probably be the easiest way to get curves from MoI over to Inkscape currently.
