Please ignore that message. It is an error in the Uplink Report. x8C is a descriptor that was first seen June 29th, 2010, at 4:27pm ET and was on every channel December 2nd 2010 at 3:42am ET. I do not know exactly what x8C is used for but I have my processor set up to report if the descriptor is added, removed or changed in length. I made changes over the weekend to track this year's new descriptors (xA8 and xED first seen August 21st at 3:41pm ET) and accidentally broke the x8C comparison in my processor. (Apparently comparing 691kb binary data files is not as trivial as it may seem. ) Congratulations if you found that information in a search.
