I think google have changed something, I got my phone in November and went through the process and it worked, had to exchange my phone early in January and never managed to get it working again, kept getting what you see on the updated screen grab. I gave up in the end, exported my calendars out of google and imported to my outlook account, works fine now on my phone, and calendars came through perfect on the export import. Google are pissing me off with there attitude towards windows phone, they used to be open everything, now they have turned into another corporate monster.
