@Nelson, please this is separate topic about upgrade failed issue, Not sure what it have to do with Amazon and Upgrade Process.
@To All Who Want to use PayPal
>....how hard they try to convince you the transaction is safe, if it's on the internet a safe transaction is simple impossible.
You try to use PayPal and provide your credit card details there, you think they are safe because they offer you to file a dispute ? Did you asked same question to Amazon about why PayPal isn't available anymore?
Something fishy here, you wanted to agree to site terms, buy a product and then after using it ask PayPal to refund you your money because you are done with product and don't wanted to use it anymore.
Have you ever heard about PCI Compliance ?
To end the discussion you should contact Amazon and Softlab directly for the question as its outside forum scope. They accept paypal for managed/hosted service only.
