For what it's worth I was trying out this software with a VERY simple Atmel minimum system just to see how easy it was to use, and although it had a few quirks it seemed ok. Until I went from the schematic to the board layout and had the auto-router route the rats-nest. I noticed something strange about the connector and when I went to 3D it was pretty obvious that it had routed one bus right over another. Unless I have done something stupid, which is possible but hard to see what on such a simple board, it would seem that a router that crashes buss lines would be a show-stopper for me.
I went to the website to raise a support issue but there doesn't seem to be a proper support point, more of a request form and no facility for uploading screen caps, so I am going to upload them here. If Iliya is checking this, perhaps he can investigate what went wrong.
