Migration from Subtxt

Hi, I’ve been trying to reach support about migrating my account. I did receive the message about signing up for Dramatica using the same email address that I originally used for Subtxt (which I’m pretty sure I’ve done), but that was the last response I’ve gotten. I’ve checked my spam folders and didn’t find anything from Dramatica/Narrative First there. What else do I need to do to get my account migrated?
