punchlight

Hi,
I have a punchlight USB relay box installed and it seems that the connection to nuendo causes the sw to freeze when creating a a new project from scratch. If a project has been opened and one creates a new project, that works fine.But if one openes nuendo and creates a new project, when pushing the transport play button, than nuendo freezes. Any one familiar with that, or has an alternative to punchlight. We use the relaybox to trigger our inhouse cuelight system.
Thanks
Carsten
