System cannot find the path specified

yesterday I changed PCs and have everything set up except I cannot watch TVE channels (antenna channels are fine) because I get the message: system cannot find the path specified. Everyone on this forum is so smart and I'm pretty sure this is an easy answer but I don't know it. Help! And thank you.

Did you attach the D:/ drive?

Yes. It’s the external drive where my recordings are stored.

The software can't find the drive it sounds like. This can happen if it's a mapped drive and you installed as a system service

What is the easiest way to fix this issue?

Is the dvr installed to the system tray or as a windows service?

Is the D: drive attached via usb or is it a network map?

via USB

There are several cache files in that folder

Is the dvr installed to the system tray or as a windows service?

I don’t know

Do you see a DVR icon in your window system tray?

Yes

Fixed. It all looked right so I uninstalled and reinstalled the app in all of my Firesticks. It’s working!!!
