Contour DVRloading issues

Hello,

Starting last night around 5pm it was difficult to change channels on the main DVRbox this has continued all day.  Tonight I unplugged the box and plugged back in the box has been trying to boot back up for an hour.  A similar issue happened around April 10th the DVR  box only was freezing scheduled someone to come out for possible box change.  It was determined our area was having issues with the guide and reboots.  It had been corrected by the morning the tech was scheduled, the tech checked our equipment, signal strength everything was good. This is the Yorktown area of Virginia.  Never had these issues with the non contour DVR box I love the features of contour but this is getting ridiculous that not only can you not use the features your paying for but you can't even watch TV at all.
