Btw, I see that you include a lot of incomplete files with your pack when I compared mine with yours with winmerge.

e.g. in admin\editstyle.php all the following is not added:

$ubbt_lang['.new-alt-newintopic_desc'] = "<b>.new-alt-newintopic Class</b><br /><br />This is used for properties of the cell that holds the indicator for new posts in a topic. This will be used on even numbered rows that are designated as new.";
