You might as well stick with OpenATV, for now, as they are all similar.
You could choose OpenVix, or OpenBH, which are similar, and appear to be the most popular.
Now that you're back to an English menu, you can go into setup, tuners and set up your Tuner motor and enter your latitude, and longitude.
Can you please post the make/model of your satellite meter?
Personally I just use a cheap, standard, meter:

The one advantage, with these cheap meters, is that it lights up, if everything is working, if not then there are only a few things, that can be wrong, Cable Connections, broken cable, dead LNB or dead motor.

If you have easy access, to your dish, you could try a new cable connection, direct from your receiver to LNB, bypassing the motor, or try a replacement LNB.
Once you post details, of your satellite meter, then other owners, of that meter, should be able to provide advice.
