I’m having the same issue and when I followed these instructions:
tools>forums>reset forums

The deletion of one set of tables failed.
I would attach a screen shot if I could.
Deleting Posts… Success!
Deleting Post Meta… Success!
Deleting Topic Tags… Success!
Deleting Conversion Table… Failed
Deleting Settings… Success!
Deleting Roles and Capabilities… Success!

Not sure what to do next.
