Hmm, I tested it, and it runs fine on my machine.
But I remember that two other players have reported a similar problem. The reason was that a civ (the Greeks) were destroyed before 146BC, and so, after the eventschange every event related to the Greeks caused an error. These two civers suggested to delete events from the eventsfile that are related to a previously destroyed civ, but I think this is not the best solution.
But the really stupid thing is that the same situation did not cause an error in other games, even with the same civ version. I tried to reproduce this error several times, but everything run absolutely correct. So I´m really unsure how to solve that. has anyone else the same encountered problem?
