Hello,
Purchased and downloaded the PDF Invoice add-on for Book it! but it seems I cannot register the download ID for the component, since it gives me an error when inside ARTIO Booking & Reservations Invoice and pressing upper right corner Options I get: 500 - An error has occurred. XML file did not load Return to Control Panel
Any tips on how to resolve this, since I cannot get into the Options at all, I am guessing, I am missing some configuration options such as Download ID etc.
*I've uninstalled and reinstalled already few times, cleared cache and so on, so the obvious fixes have not worked.
Any help is appreciated.
