It looks like in the last couple of days some of the Paypal IPN notifications for your donations did not include the Soulseek username you provided. This has never happened before, and is probably a pretty serious problem on their end. We did run into a similar issue a couple of weeks ago where the username was sent as a differently named field in the IPN notification (which also never happened before), but we were able to adapt to it on our side.
We tried calling them but there doesn't appear to be anyone there who can help us right now, so we're going to keep at it until they can resolve the issue. Until then, we'll be manually activating privileges for affected donations by hand, so we appreciate your patience as there's a chance you won't receive them right away. We're hugely sorry for this inconvenience, and as always we greatly appreciate your support! If a day has gone by and you still haven't received your privileges, please post about it here and we'll take care of it ASAP.
