The problems you seem to be having with V13 does not surprise me. In comparison to my problems these are chicken feed.
The only way I was able to sort out my problems was to remove V13 service pack and run ACAv13 alone.
Autodesk know of the problems for I have emails confirming this but for some reason I believe have chossen to do nothing about them.
I am running V13 without the service pack 1.
