Warhammer3025

Sorry if this has been posted before (nothing turned up in my forum search), but I've been having a problem with during my second playthrough. I enabled the Developer's Commentary mode for my second go-round, but every time it triggers, the commentary is cuts off abruptly before it finishes. I'm reasonably sure it's nothing I'm doing, as several times I've simply sat idle, not even touching the mouse or keyboard, and the commentary still cuts short. I know it's not a huge deal, but any help would be appreciated.
