Pro Site didn't upgrade

Hi Team,

The new Pro Site plugin is and it works fine.

But the last time the website didn't upgrade to the next level.

This is what happened:
- The website was extended to 17 nov manual by me
- On 16 nov she upgrades her website. she pays by paypal
- On 17 nov, paypal says: the payment is ok

- but her website didn't upgrade to the next level: "Zakelijk"

Do you know why? This is the screenshot:

Thank you in advance, Stijn
