Glad you were able to get it all to work.
My understanding is that the error messages are "harmless", but they are annoying.
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.
