802.11 wpa-pwd decryption not working 1.8.2

I have been searching around for someone else who has had the same issue for a little while and have given up. I was attempting to decrypt the traffic on my network which is using WPA (Personal) with Wireshark's built-in decryption key's tool and have been unsuccessful so far.

I then tried decrypting the wpa-Induction.pcap (http://wiki.wireshark.org/HowToDecrypt802.11) capture file and had no luck. Before I revert to a previous version of Wireshark where decryption was working (according to other posts here), does anyone have any suggestions to resolve this issue?

Thanks
