Hey Frank,
Thank you for your purchase and welcome to our premium support forums! You can visit our Refunds page and we’d be happy to refund your iCal Importer purchase.
Can you walk me through the steps you took to acquire the Google Calendar link you shared with me in your follow-up response? (https://calendar.google.com/calendar/render?pli=1#main_7)
The correct URL for your Google Calendar can be found by navigating to Google Calendars > My Calendars (left-hand side of the screen), then selecting the dropdown arrow next to the calendar you want. From there, you’ll select the ‘Calendar Details‘ tab and scroll down to the ‘Calendar Address‘ setting and hit the green ‘iCal‘ button.
Please let me know if these answers help and thanks again for choosing us for your events calendar needs. Cheers!
