Have the Keys rolled again?

i lost a few chanels during the week, bu came home from work tonite and found that all my keys were wiped all at 00. Dont know if someone in the house done anything to box or unplugged it, but this has never happened before, after putting keys in again all i have is rte1 and network 2, has this happened to anyone else. I use bigmac tool bar to get keys, but these were last updated on 25th of last month.

Anyone have a explanation for me ?
