There must be a problem with your paypal account because other clients can purchase our extensions without any trouble . There is another way to pay is using bank transfer . Could you try to find an alternative solution for your project ? Like a simple donation module or something like that .
We don't block any account of clients . If you purchased the extension before, you can simply submit a support ticket contains the email and transaction id you used to purchase the extension . We will assign order to your account so that you can download future versions for free . For all our extensions, you just need to purchase one time and download for lifetime .
I will go to bed now . I will check email, support ticket and reply you on my morning .
