In PandaPow version 2.3 in Windows, and later a newer version of the TAP adapter is used. The newer adapter is better in most cases, but it appears to cause problems for some users. If you have issues connecting or crashing, you can try to switch back to the old adapter.
Open PandaPow Settings and choose the Debug tab:
Click button Install old TAP. This will open a Command Prompt as seen below.
Once the installation is complete you should see a message in the Command Prompt saying Drivers installed successfully followed by Press any key to continue …
Press any key to close the Command Prompt.
On Windows XP you may need to restart your computer after re-installing the TAP adapter.
You should now try connecting PandaPow again.
