Regex columnizer doesn't work

[TheNicker]

Got an unhandled exception.
To resolve that temporarily I've added:

configurator.LoadConfig(ConfigManager.ActiveConfigDir); at

LogExpert/src/LogExpert.UI/Dialogs/FilterSelectorForm.cs

Line 119 in b5caaab

configurator.Configure(_callback, ConfigManager.ActiveConfigDir);

Seems like loadconfig doesn't get called.

Please review for a better solution.
