Ah, I didn't see that. However, you can at least test it out in the meantime. You can install the free version, then go to Google Calendar and export your calendar(s). Then go to Rainlendar and you can import your calendar(s).

Then you can play around with the program to see if it works for you, and decide if you want to pony up for the "Pro" version.

Then again, like you said it isn't very expensive
