Thanks a lot for figuring out the problem! I feel so sorry that the app error 200 happened on your device.
Since 1.5 release, I've seen many downloads and activations. I believe many of them are upgrading from 1.4 to 1.5. I didn't get any error report besides yours.
I appreciate you very much for testing 1.5 as well. It identifies a small bug in call log handling.
