Subsites are down if previous payment gateway was paypal express/pro

Hey guys,

after the latest update i've seen that a few sites on my network were going down.
Only sites that had PayPal Express/Pro as the previously payment gateway are affected.
They expired and should now be running on the free level.

I get that error:

Fatal error: Call to undefined method ProSites::get_profile_id() in /Applications/XAMPP/xamppfiles/htdocs/mywpinstalation/wp-content/plugins/pro-sites/pro-sites-files/gateways/gateway-paypal-express-pro.php on line 3146

This error exists locally as well as on my main site. Support Access Granted!
Best,
David
