Trouble with cancelled plan

I had an Adobe account under one email and password.  I cancelled it and started another account under a different email and password.  Every time I log in on IMac with the new email and password, Lightroom wont let me into the Develop module.  I get message saying my account has expired and I have to sign up for new plan.  I have a plan as I stated and I'm being billed monthly but I cant use it.  I've cleared cache, history, etc., and have even tried Safari and Chrome.  I can however access the account on my Dell laptop but I prefer the IMac.  I've been on Adobe Support Chat several times and they recommend the steps outlined above, but I get the same result.  Suggestions appreciated.
