Hi - i am running openpli 3.0 - cooltv 6.03 and crossepg and have a full epg including now and next - infact this was a key reason for me to move to openpli from BH.
I would try to delete/rename the epg.dat file and crosepg directory on your hard disk, download the epg again and restart enigma.
Only other thought is that you may need to set up a swapper file - but i havent worked out where to do that in openpli
