just updated to 5.1.8 and updated templates. one help system works, but main help system claims template error for all entries. have a couple more to try.

Hi Bill,

Make sure you update your templates.

Old 4.x templates will not work with 5.x projects. Use Tools->Options->Update Templates.

Help Builder backs up your old templates - if you've customized your templates you will likely have to backport changes into the new templates using diff tooling or manually pushing changes into the new templates.
