I get this on both GB-PVR and DVB-Viewer, something seems to have broken

I have reinstalled all my Hauppauge drivers and still nothing.



I run two DVB-T cards in the box (only one is being used), but it's worked fine up to a few days ago.

What next?  I tried to uninstall and reinstall mmaace.ax (which i'm pretty sure is the right thing)
