Hi Estephania,
Here is the error message in the pop-up window, wireshark-2.1.0 Thread is in the backdrop tapping on "Local Area Connection 2" as used by Kinetis protocol adapter.

Earlier, I had been using Kinetis Protocol Analyzer Adapter and Drivers 1.0.1, which used to work fine. Nowl I have installed Kinetis Protocol Analyzer Adapter and Drivers 1.2.6 on the same machine, which is behaves in an errant way.
FYI, tried a different version of Wireshark and WildPackets Omnipeek analyzer to sniff the packets on the interface "Local Area Connection 2" without any fruition.
Let me know if you need any other inputs.
Thanks!
PS: There is no chapter 5.1 in the Quick Start Guide to help resolve this issue.
