I'm currently a trial user of your software and ready to make a purchase. Went through the process and tried to pay with my American Express. Entered it on the site not realizing I have to go through PayPal (??!!) to pay with Amex. The site gave me an error message. I then realized I had to go through PayPal, which didn't work as that Credit Card is attached to an existing PayPal account, which I have not used in ages and which is therefore deactivated (I don't plan on reactivating it). I then dropped it and did not look into this for a few days. Today I was going to try again and was quite negatively surprised that you apparently stored my Credit Card details in PLAINTEXT in my session, so that as soon as I as arrived at the checkout page again, my complete number, including expiration date was visible. I'm pretty sure that is in violation of PCI compliance and could have led to serious problems if I had used - for example - someone else's computer. Please fix this.
