HI, I've upgraded from 5.2.0f to 6.1 then to 6.2.0 beta
When i try to create a new appointment in the agenda I get this :

Catchable fatal error: Argument 1 passed to TimeDate::get_date_time_format() must be an instance of User, boolean given, called in /home/mysite/public_html/sugar/custom/include/Calls/google_calendar_plg.php on line 92 and defined in /home/mysite/public_html/sugar/include/TimeDate.php on line 377

Need help, thank you
