Contact form and payment solution not working

Hey there,
I was trying to purchase a license for the pro version using 2 different cards and via paypal but to no avail. Payment provider tells me my card number is incorrect. Which it isn’t.
Also the purchase couldn’t be completed via PayPal. That’s strange.
Then I tried contacting you via your contact form which only states “There was an error trying to send your message. Please try again later.”
So here we are in the WordPress support forums, hoping this will get sorted out.
