System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize

[ludo237]

Hello. I would like to report an exception, and a possible working fix for it.

Problem

Idle Master stopped working

Possible cause

I rebooted my Computer with steam and idle master opened.

Current Patch

I've removed this folder: C:\Users\Ludov\AppData\Local\IdleMaster and everything went back to normal.
