When using Cad File Manager “Database Version Converter” to version up your Board Designer data there is a limit to the number of versions you can version up.  This limit is 3 versions.  If the data to be versioned up is more than 3 versions from your present working version, you need to use “Update File Version” or run zdbevolv.exe from the command prompt window.

Run "zdbevolv Design Name" from the command line the database can be updated from more than 3 versions back.

From the cad File Manager RMB on the Design Name/[Board] -> Tools -> Terminal. then run the command line "zdbevolv Design Name" this will uprev to your current version.
