When I bring up Themes (left arrow) and pick a category, the program list opens and then immediately closes. I have used Themes in the past with no problems. I have plenty of disk space left (126 hours SD or 18 Hours HD). I only power the receiver on for 3-4 hours each night when I watch programs. I did a power reboot but this did not fix the problem. My Receiver CA ID is R0066164701-07. My SW Version is L213HEED-N. My boot Version is 150B. I contacted Dish technical support and the technician was unaware of this particular problem. She had me check my signal strength on 105, 110, and 119 on several different transponders and all signal strengths were excellent. She then made out an incident report since she claims that my problem is not documented. Is this a new bug or is it just unknown to the DISH Technical support? Also, is there any known fix? Thank you for your support.
