So you have a 7.4X on OS/2 and seemingly migrate the database to a Repartee for Windows. Accessing the subscriber directory through the Administrator's tool then blows a horrific error on screen referencing XML parsing.
Me thinks it has to do with foobared AV*.AV* files (since I know at least some of the PBX integration files are XML).
NEC support says simply run voiceserver dbchk /f a few times after backing up the AV*.AV* files.
Simple, yet undocumented.
Thanks John K. for not making me work late tonight.
