I think you need to determine if the adapter still exists on your computer from the screen-shot it looks like it does not. If that is the case then you need to get a new file from PTC.
If it does exist on your system it may be that a different adapter is active and that may be preventing the software from detecting it. If you disable all the other adapters and enable the one with the correct mac address I think it should work.
To check if your computer has a network adapter with that MAC address you can run the following powershell script:
$a = Get-WmiObject win32_networkadapterconfiguration #-Filter 'ipenabled = "true"'
foreach ($adapter in $a){
$b = Get-WmiObject win32_networkadapter -Filter ('index = ' + $adapter.Index)
if($b.MACAddress -eq '74-EA-3A-94-B8-82'){
Write-Host "Network Adapter Found:" $b.MACAddress
}
}
To run the script click the windows button on your computer and type powershell ISE you should see "Windows Powershell ISE" show up in the list. Open it and paste the code into the editor and press the play button. It may take a minute or two to run depending on how many adapters you have. If you have the adapte ron your computer you will see the script write "Network Adapter FOund: <MACADDRESS>". Hope that works for you.
