Fixed Bug: No changes are saved to advancedsettings.xml! 

If cbTVGeneralLang.Text is empty (= no TV language is  selected/set by user)  no AdvancedSettings.xml will be built/saved (or any changes to that file!) 

Noticed that problem when I made fresh install of Ember and tried to change Advancedsettings! Got error notification! After I set TVLanguage via Fetch language button on Show Tab, settings are saved again!
