I don't know if you've been following TagFest of facebook, but there might be an issue with the software.
I wasn't able to go, but I loaned my device to Paul Borella and they had issues with it.
According to Tod, this happened
I'm not sure what version Paul was using, but I thought I would let you know about this.The Lazer Swarm couldn't handle games over eight players due to a coding issue. It sends out an incomplete countdown signal causing the first eight taggers to ignore tags from taggers nine and above. I imagine it's an easy fix, but it's a game killing bug at this point.
