You should post the log you find in /hdd, so perhaps we can understand. There is ImportEPG Plugin if I remember well, that is good and supported by OpenPLi, as they let down the CrossEPG but it works on previous versions.

Be sure that you have an HDD when you use CrossEPG, it's NECESSARY as it swaps all data to it before completing the data, and then the result of the data is still stored on the HDD, as the Flash is far too small to contain all the EPG data.
