Next fails to open any of my existing Band Lab projects

Please help

I might be misrembering, but I think Next has it's own format, or can open the new shared format that Sonar saves in.

To open .CWP files from CbB, I believe you must use Sonar.  If this is the case, then once open in Sonar, you could then resave as a new file using the new shared format with Next.
