Time registrations are not shown in Invoicing software after upgrade to premium

For invoicing my clients I use API to transfer the time registration to the invoicing software. Yesterday I upgraded Toggl Free to Premium. But now all my registrations are not shown in the invoicing software. the API is correct (copy - paste into settings invoicing software).
There must be something wrong with the upgrade. Anyone who knows how to to solve this?
Much appreciated!
