Oh, I finished events and they work great.
So, old EventList had 7 tables, and JEM has 10 tables
And in jem_events are 96 colons, but in old cal was 26 :-D
But I opened all of that in excell and restructured like new tables and put into JEM through Administration (Impoet csv) and it works great now.
I had problem with events which are repetiting, because JEM maked new events all the time, and I had error but I solved it with put all 0 in 3 columns so no repetitions for old events now. and no error or problems
