A VERSION OF ENGINE DJ IS ALREADY RUNING EnginE dJ Wont Start Anymore

[DJSeppie]

Check this post, perhaps it is the same problem:

Engine DJ is starting, but there is no windows

Open Engine and make sure it is open. press ‘Alt’ and ‘The Space Bar’. A little menu pops up, select ‘Move’ and now you are able to move the window using the keyboard arrows. This behavior can occur when you move Engine to another monitor and the next time you start Engine without the monitor connected. I hope this helps.
