I was hoping someone would have tried something like this before so they could help me. I'm having a problem with the LoadLibrary line i'm pretty sure. Wireshark will load, but when i go to dissect my packets, it freezes. I'm not sure how to fix this or what exactly is happening. If anyone could help it would be great.

Is there a way to tell why it is crashing? I'm not sure what the cause is.
