That happens a lot. You just get counted as a new ACTIVE user, which for the reasons described in my first comment may be a better success indicator than signups.

Actually that’s why I run “thaw campaigns” to reactivate past (now inactive) users. Something as simple as a reintroduction email to users who’ve been inactive for 6+ months, calling out new features and benefits and success stories. It brings back a lot of people like you, whose situations changed and might now have a use for the product.
