hi
what is the google email you used for support?
thanks

I'm not sure. When the error message came up, it just gave a link to click for help. The link suggested going into internet options of IE and deleting cookies/cache/history and then asked if it helped. If you click no, it then gave me a window where I had to type in my name, email address, brief explanation, how long the problem and the name of the missing calendar, and then push submit.
There was no email reply, but a few hours later the missing calendar came back. But then another calendar went missing. I did the same thing and that calendar was eventually restored on google. There is also the help centre with a help forum that has been discussing this missing calendar issue over the last two weeks. It appears to be a server issue which affects about .01% of google users.
After I got all the google calendars back, I still suffered an endlessly-going-nowhere sync. The sync icon would always be on and both the Android and Calengoo calendars would freeze and no new events would sync in either direction. Eventually, I went into Applications-running applications and deleted the cache storage in the calendar storage. That got rid of the the sync issue.
I have 10 years (about 8 mb) of stored calendar events. Android only lets you sync back the last 2 months of events. In the past, I always tricked it by resetting my Android date to 1999 which forced it to sync all 10 years of data (you only have to do this the first time you sync to get all the old data in; after than you can reset to the current date). After this sync problem, I switched over to Calengoo's direct sync option which is designed to sync all historical data. The first sync took about 10 minutes. But all subsequent calengoo syncs have been really fast (30 seconds) compared to the Android syncs (3 to 4 minutes each time). Hopefully I won't have any more problems. (Note: there will be some duplication of calendar events (2months back going forward) from Android and Calengoo, but you can disable the Android calendar or make them invisible).
I am glad I backup my google calendar onto Pimlical desktop from time to time. This google glitch really freaked me out.
