Added: New troubleshooting options have been added to the Configurator that can be tried in case of problems. Improved: E-APO is now normally always installed as LFX/GFX, also in Windows 8.1 and later, to avoid problems with some applications bypassing SFX/MFX APOs (e.g. Skype). Fixed: If the input channel count was higher than the output channel count and there was no child APO, Equalizer APO could crash during initialization. Fixed: If a file in the config path was only renamed (not modified), the configuration was not reloaded.
