Clicking 'Live TV' in desktop app gives XmlException: Root element is missing

[jwh7]

This machine never had v4.  v5 was working fine until after the first time I used time shifting (which worked fine), on 5.0.1.200209 (I think) but the same issue still occurs now on 5.0.1.200322.  Ever since, I get this error popup (details in zip file).  Sometimes the video would still come up, but freeze after a short time, other times I have to force exit the app.  The web app still works fine though (before and after).  Figured I'd ask here first before I just wipe everything out and start from scratch...

Did you ever install before? The server is running from a different folder than the client.

Does running c:\Program Files\NextPVR\client\NextPVR.exe change anything?

I normally run it that way yes.  It's the same from there or via systray.  Not sure what you mean about installing before?  I have used the v5 windows installer since it became available with 5.0.1.200209, as already noted.  :-)  And also as previously noted, things were working fine until after I used the timeshift function.  It may be coincidental, but is a fact. :-P

I forgot to mention, if I run the separate server, as was requisite before the installer's service setup, it crashes (not sure if this is related or just due to the new service setup):

That wasn't my point it appears that the client is from wrong folder the one from an old install and I wanted to be sure you are loading it right . Now it sound like the wrong tray app is loaded.

I did find that the new installer had installed to a new default folder than the one I had used with the manual process (I didn't get a setup option to choose a custom install location).  Exiting the tray, stopping the service, and deleting both directories, and reinstalling didn't help though.  What did fix it was deleting C:\Users\Public\NPVR-data\ and manual setup again.  All is fine now, though I am now reminded of an issue I've seen all along with v5.  In the desktop app when watching a channel, the right-click menu option for Main Menu doesn't do anything.  I've been using 'Stop' as a workaround.

That is what I thought. Here is the step you should have followed https://forums.nextpvr.com/showthread.ph...#pid534784

The custom install location option is only for new installations and you already had one.

> Either way do NOT delete the data folder in C:\Users\Public\NPVR-data

In my case though, I still had the original issue after deleting both installs, until I removed NPVR-data as well.  I didn't have any recordings or anything; just channel and decoder setups needed.  :-)
Thanks for the hints though!
