Hey Farhad,
WPML is not compatible with The Events Calendar even right now, at this present moment, unfortunately. So earlier versions will not be compatible.
We are working hard on improving this compatibility, and since the Community Events ticketing functionality will just “inherit” much (if not all) of its translation capacities from The Events Calendar core, then hopefully when The Events Calendar itself is compatible with WPML all of its add-ons will be, too.
At this time, however, such compatibility does not exist.
Sorry to bear the bad news! Let me know if you have any other questions or concerns 🙂
