BUG Clearfy lifetime owner , old account lost

[Kosapan]

I own a clearfy lifetime licence for 3 sites since a long time. Today i saw that my clearfy installs are returning errors and wanted to signal it ... none of my emails are registered wit webcraftic anymore and had to re create an account ... what happens if i have a bug and need to get my license keys? or need to move my licence from an old site to a new one?
