Guys, I just updated the program but now it's on free mode again. I can't find the license file or email and I'm in the UK so Paypal is not being very helpful (their servers are not letting people into their accounts and customer service just wants me to ring in the morning. Again.).
Any ideas? I've tried all the usual stuff to try and get into my Paypal account so I can at least send in the payment ID but I'm not sure what to try otherwise. ;_;
