Thank you for contacting us. After you delete your account, the only thing you can do moving forward is created a new one. After you create the new account, then you would start from scratch or restore from a backup you may have.
Regarding your subscription, I only have a few different ways to locate it, and I was not able to find one with the email address you are using here in the forum. Before you create a new account, let's try to figure out if I can find your subscription first. What type of device were you running mSecure on when you deleted your account? I assume it was an iOS device, but it may have been a Mac computer. Also, did you purchase your subscription from inside mSecure on either your iOS or Mac device? If so, do you have the receipt for that purchase?
Unfortunately, we don't have any record of your account ever existing in our system, because when an account gets deleted, all traces of any data, including the email address and any data associated with the account, is removed from the system. To be clear, if you purchased an mSecure Pro license in the mSecure 5 app, that license gets deleted when the account gets deleted, so there is no record of your purchase in our system. I have no problem applying a license to a new account, but I have to have some way of knowing the license was purchased. Does that make sense?
What I need is not an actually receipt. I just need some proof that you actually purchased the license, because right now, I have literally no trace of you in our system. To find a purchase from 2017, or any year, you can follow the instructions in this Apple help article: https://support.apple.com/en-us/HT204088
After you find the purchase, just take a quick screenshot of it to show me the purchase.
Did you check your Account Settings to see if mSecure is showing that you have an Essentials account?
