Cannot access account

Hello!

I am having issues with our theme and have a few questions. When I tried registering by entering my item purchase code it said an account already exists. I tried resetting the password but then realized that password reset will not go through because the employee that set up this account left a number of years ago. I’m not even sure what email it would be tied to. Can you help? Sorry for posting this here – I cannot find another method of contacting you.
