Just downloaded and unzipped 10-vc2. Of 11 projects I was working on in NB 9.0 10-vc2 describes 5 as "not valid or deleted" when I try to open from "Recent Projects"
However, I can open some of them with "Open Project". Also, I select plugins installed in previous version but the "Import" button never highlights, just the "Don't Import" SoftWoehr LLC <http://SoftWoehr.Com> Legacy Transformation using Open Source Software
