But why do you want to use Paypal to buy bitcoin? This is against the terms of services of Paypal and if Paypal finds out what you are doing they will close your account as you have find out already, also if you want to buy bitcoin with Paypal in this forum it is possible you will get a red trust and if you do it in some other place then you will probably be charged twice as much or even more for the risk the seller is taking.
