I haven't received payment either. As per the shared excel sheet, it seems that just bitcoin31 has gotten payment for last weeks campaign. I have sent PM to the OP and am willing to wait for another day. Meanwhile, I'll PM bitcoin31 and ask him if he did receive payment.
Edit: I looked into his address for receiving payment but doesnt show up any payment done in the last few days. So, most probably just an error in the excel sheet.
Paybs was online about 12 hrs back, so hopefully he'll be online again soon. Its 8:30 AM in Latvia right now, so potentially anytime now.
