Description of issue: Sonarr has been running fine for a while, following a PC restart a “Epic Fail” error is displayed each time I try run the program. Message states: FileNotFoundException: Could not load file or assembly ‘System.Numerics, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089’ or one of its dependencies. The system cannot find the file specified.

I’ve attempted to uninstall and reinstall the application, however the same error is still displayed.

I think the file being referenced is part of .NET. The November .NET framework update just released. Check your Windows Update for recent or pending updates. Complete those and see if it fixes. Otherwise maybe try reinstalling the .NET framework components.

I completed the updates but this didn’t resolved the issue. However a reinstall of .NET framework did fix it, thank you.
