This is weird, but I have had this issue before. I only was able to fix it by removing it with the code you sadly don't have. I know their customer support can help you as well, but yeah... they won't be available either. Do you still have the registration code in your main, trying to delete the app and re-register it again with it? I don't know if they are one-time use. Have you tried adjusting the time in your phone too?
