The reason your account was not activated is that you signed up to the $1 trial, cancelled, and then tried to sign up again to the $1 trial.
We only allow each user to access the $1 trail once (tracked by Paypal account). In-fact you tried to do this a total of 8 times.
I have re-activated your account and set it to expire 1 month from now, as there is no current active recurring payment set up for your account.
After your pro membership has expired, you are welcome to re-sign up, but please know that when you cancel your recurring payment with paypal, it cancelled your membership immediately.
