I've reached out to Support (request #6397).

Was already trialing Premium at $9/mo. For some reason the system is counting that as part of the stack and is preventing me from adding my last code.

Error message I'm getting: "You have stacked your account too many times (max 10)."

Obviously I would like to stop the trial and add all of my codes.

Could someone please add my 10th code to my account for me or tell me what I need to to do add this last code?

Thank you in advance!
