Hi
I have been going thru the ADN video on updating code from vba to vb.net and have gotten everything into vb.net but the references do not seem to work the path names are not the typicsl ones I would expect and when I change them they convert back to the original paths that do not seem to work any ideas.
From the reference versions, it looks like you are developing on 2012.
If that is so, check out this post which covers issues with 2012 com references, including a fix.

or check out this post on adn dev blog on the same issue with fixes.
Hope this is the solution you are after.
