Tvheadend

Hello all.

I have tvheadend as backend on my openelec install. Until now I haven't had any problems with the EPG.but a couple of days ago it's suddenly only started showing a couple of hours in the future. and some channels don't even have EPG information.my tuner is dvb-s and I haven't added any xmltv files, I think I am using The over the air grabber.

I have tried everything to make this work again...so that is why I came here. It is very frustrating, and not very wife friendly any idea how to fix this?
