Lost cable with latest cable box software update

This past Sunday we lost cable due to the latest software update Cox pushed out.  The box kept attempting to reboot and  after each reboot attempt we got a “bad image file” error message. So, a Cox tech came out Monday evening and replaced the box. Then on Wednesday, same problem with the new box. The software update caused us to lose cable again, and we get the bad image file error message after each reboot attempt. Another Cox tech is coming out tomorrow, but at this point I’m not confident that after another box replacement we won’t have this issue in another few days. 

Is anyone else experiencing this issue?
