EBTrivialScript Error

[LorDBulA]

Well, I had very similar thing with "preferences", but the reported error was "error 3" => there was neither preferences.txt nor Eb/preferences folder, there was only preferences.xml file.

This is normal. If you try to configure Preferences before you start EB for the first time you will always get this error.

Why?
Because preferences.txt file is generated by RTW depending on your computer hardware. Because of this its not present in EB installation.
After you start EB for the first time RTW will generate preferences.txt file that you can change.
