Lightning no longer working with Google Calendar

I've been synching Lightning with Google Calendar for over a year 
without any problems, but today when I opened Thunderbird no events were 
being displayed in Lightning.
I tried deleting my Google Calendar in Lightning (i.e. in Lightning, 
under "Calendars" in the left pane, I right-clicked on "Google Calendar" 
and selected "Delete"), but now it won't allow me to re-create the 
calendar (I'm trying to create it using the method described at:
https://support.mozilla.org/en-US/kb/using-lightning-google-calendar).
When I select File + New + Calendar, then select "On the network", then 
click "Next", and then select "Google Calendar", a "Location" text box 
should be visible in which I should be able to paste the XML location of 
my Google Calendar - but no such textbox is visible. In the dialog box, 
the "Location" textbox *is* visible for any option I select other than 
"Google Calendar", but it disappears if I select the "Google Calendar" 
radio button.
I wondered whether the Provider for Google Calendar add-on might have 
stopped working properly so I uninstalled and reinstalled that, but 
doing so made no difference.
Thunderbird appears to have just upgraded itself to a new release and I 
wondered whether this could have caused the problem? If so how can I 
undo this upgrade? Being able to synchronise Lightning with Google 
calendar is absolutely critical for me.
I'm on Thunderbird 31.2.0, Lightning 3.3.1 and Provider for Google 
Calendar 1.0.1.

Update: downgrading the Provider for Google
Calendar to version 0.32 appears to have fixed this. Does anyone know 
why this might be and what functionality I will lose from doing this 
downgrade? I can't see any obvious loss of functionality but there must 
be something or version 1.01 wouldn't have been released in the first place.

Those instructions are only valid for old releases of the extension. In 
the current release you don't need to enter the calendar address 
anymore. Just proceed with Next and enter your Google email address on 
the following page.

That didn't work when I try it and in any case Philip (the Provider 
add-on's developer said in another thread that the current release or 
the Provider isn't working and he advised people to downgrade.
