Calendar+ sync problem

Hello, I want to use Calendar+ app on my Passport, but meet strange thing - it can not sync with my google account. The thing is that native BB calendar syncs and shows my events, I can sync contacts, but all not native calendars can not sync. It even does not allow me to choose account I want to sync and drops me into account edit menu. Any thoughts?

Thanks

Calendar+ app may need Google Services (which you don't have). :-(
