Afilias has changed there whois format in accordance with ICANNs requirements. This is a try at updating to parse the new format.

For the record I ended up starting my fork in which I fixed all the Afilias based whois parsers (.ME, .ORG, .INFO, .PRO, .BZ, .GI, .LC, .MN, .SC, .VC, .AG, .IN, .AERO, .ASIA, .MOBI, .POST, .XXX) in e2b84e7. So people who need this can use my fork:
