looks like they just have a break yesterday evening.
I don't think so, otherwise you would have seen a lot of similar posts over here. At the moment, your post is the only one.
Seems that your internet provider had a break or any other problems within your receiver... There was no problem with Polish channels during those days.
P.S. Reading your signature, I see that you use cccam (2.1.1-2971). Seems that you don't read the forum and do not know that we recommend using Cccam 2.3.0 verion. Last times, we talked about using MgCamd 1.35, or newcamd via cccam, I see that you use only cccam emulator with cccam protocol. Why? You have to mention that this bundle is not working properly with your receiver, you are facing regular problems. Maybe, this is time to think of some other receiver? Nboxes are popular, I know, but they are not the types of boxes good for our server.
