Contour1 TV grid only updates 8 hours
My Contour1 TV grid didn't update last night. I powered off the box and when it rebooted, the first 8 hours updated normally, but the remaining grid never updated. A Contour1 (Cox TV) grid normally updates for the next 13 days. I then used the Cox website to reset the box. When it rebooted, the only change was the grid displayed a new eight hours, starting from the fresh reboot. I contacted Cox and was told they sent a passive channel update signal to the cable box, but it had no effect. I later rebooted again with the same results.
Cox is telling me I need to replace the box. I'd like to know for sure it's not an issue with the TV Grid update software before I replace it. Has any other Contour1 user experienced an issue with the TV grid only updating the initial eight hours?
