Unhandled Exception fot TV Guide after Updating to 3.8.3

[GWCowling323]

After upgrading to 3.8.3 I get an Unhandled Exception when I select TV Guide:

Method not found:
'System Collections Generic List.....

Does it look like updatedb will work as has been suggested in other threads?

NextPVR starts new log files each time that the frontend program starts and each time that the recording service starts (and also when the existing log gets big).

The npvr.log that you have attached is for a 5 second period at 04.45. I cannot see that any error occurred at this time.

Please recreate the problem, zip and attach all of the logs in the logs folder to a post that tells us the time that the error occurred so that we know where to look in the logs. Thanks

Running "-updatedb" will do no harm even if it is not the solution to your problem so you could try it.

In addition to including the log files, here is a copy of the details when the problem occurs:

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

If it was me I would

- stop the recording service
- remove "C:\Program Files (x86)\NPVR" folder,
- rerun the installer
- run "C:\Program Files (x86)\NPVR\NextPVR.exe" -upgrade

and see what happens.

This will keep your existing configuration but you still might need to do a database empty and load from the Settings.

I have exactly the same problem. It has happened since the Win10 anniversary upgrade.

This error is saying that the upgrade failed to install some new components (presumably because they were already in-use), so you ended up with some old DLLs still on your machine. Stop NextPVR and reinstall, then you should be good to go.

Reinstalled this morning and everything worked great. Database was there. Recordings I had scheduled was there. All other settings were still there.
