MailPoet: I want to start again from scratch

I have done something wrong when I tried to install MailPoet and create an account. I suddenly had two subscription plans (free premium plan), which both gave me an activation key that both didn′t lead to the premium plugin being installed. I tried to manually download it, but since the ReadMe said that this is an alpha test for developers only, I got scared.

So I wanted to start again from scratch, cancelled the two plans and deinstalled the Plugin. So here is my problem: I now have two cancelled plans that seem to count towards my 2 plan maximum, so I cannot get a new subscription plan.

When I install the Plugin again (it was completely deleted, not just deactivated), it still knows that it is connected to this account I messed up with the two cancelled plans. I didn′t find any way to connect it to a new account.

I have also tried to undo the cancellation of one of the free plans on the MailPoet website, but this doesn′t work either. I also didn′t find a way of closing my account wih MailPoet or anything of the sort.

Does anyone have a good idea what to do? I am incredibly frustrated and just want to undo everything and start again.

Thank you so much for your help!
