i meet the similar problem to you. i dont know which file was deleted or which application will disturbe the virtuoso.
The virtuoso tells me an error: ddMapGetFileViewType: argument #1 should be addUserType (type template = " b") -nil
how can i solve this problem?
Any guides or helps will be pleased.
There are two files (dfII and cadence.signature.xml) in the .cadence file. And the old .cadence file has history, Navigator and viva. The history file has only one file "root.history", it tells me about some cellview I opened before. And the Navigator has Option.xml, I can't open it with firefox. The viva file is an empty file.
Is that help you to find the problem?
