LDwin keeps posting my own mac address as switch name and gives no info

[TiberxGit]

This has been since a couple of months.
Already tried reinstalling network card, Windows Firewall, Troubleshooter.
Have read all the tickets, asked all my coworkers, but nobody seems to have the same problem.

If i open the program, select a network card and click on Get Link Data it will instantly show my own mac address and nothing else, i can scan multiple network cards but they all show the same result, I've also tried multiple switches but nothing works.

Thanks in advance for your help.

See screenshot below,

I fixed a similar issue by deleting my %temp% files. It seems like the tcpdump program crashes and locks the SaveData.txt file which is what is displayed to you in LDWin
