Problem editing nodes after importing vector

[tnt_racing 3]

I use PhotoImpact X3 to convert photos to black and white image (clipart).  I then open the b&w in Inkscape and trace the bitmap to create a vector image.  Then I import into SBE to cut.  However, sometimes, I want to edit the nodes to clean up the image a little in SBE(I find that node editing is simpler in SBE than Inkscape), but when I click Edit Nodes, and the stop editing, the image disappears.  Has anyone else had this problem?  What can I do to fix it.

Also, when I start, save, import, or do just about anything in SBE, the trial mode screen comes up, and counts up the number of times I have used the program (currently counting to over 250).  I have done everything that I have found to get rid of this screen, to no avail.  Any help here?

Thanks,

Jeremy

I have found when this happens it is usually bacause there are breaks in the geometry or crossing lines. CAn you post one of the SB files?
