Hi man,
Running it on Windows 7, There's no visible blue highlight anywhere, nor is there anything in the code that sets the menus' highlight color (http://getmusicbee.com/forum/index.php?topic=2917.0) to blue. maybe an OS derived color or something like that.
There is a problem though with one of the image elements in the file, causing MusicBee to run out of memory and crash as soon as it loads it up. might require you to check them one by one to find which one is the problem.
Best of luck,
Just downloaded the new skin, moved it to the proper folder (C:\Program Files (x86)\MusicBee\Skins) and tried to choose the file from the menu. The following error occurred:
