beware of the update!

After a long time using this plug in, which I found reliable and nice, I faced the surprise that with the last update ALL the previous events were lost!…I tried to have some kind of help through the forum but none of the developer did answer. I know it is a free plug in, but at the least an answer would have been polite! Now all I all I can do is find another resource and quit event-list for good…
