Quoted from SpookyCharlie:
Check your spam filter, and if you have any questions, email@example.com will get you taken care of. Emails regarding this change went out last week.
We will no longer be using PayPal to process any game sales... everything will go via our own merchant account. Sorry for the confusion and inconvenience!
Spam folder was the first place I checked. Nothing in my deleted emails. Paypal refund note said to check personal email sent 1/4/16. Oh well, KT pm'd me the email.
