Troubles with google calender under TB 3.01

I used the Provider for Google Calendar in TB3.0.1 portable to sync my google calendar.
It's work fine at home pc which I set the google calendar's username/password first, but if I run the TB3.01 in others computers, The TB can't link to the carlendar, it always request the google calendar's username/password.

I try to delete the calendars and reset them again in others PC, I check the "saved passwords", and there is not save the google calendar password still.

Why? Please help me.
