Sadly, because of the way XXHighEnd communicates with her #3/#4 Audio Engine, "Dos 8.3 Short Names" must be supported by the OS;
In normal situations this is just the case, so no problem. However, the Short Names can be switched off manually, or can get shut off in the process of (OEM, Other Equipment Manufacturer) generating the OS on the PC.
In the latter case all kind of errors may appear during the useage of XXHighEnd, and they usually come from the ChangeWP program at (the impossibility of) showing CoverArt.
The maintaining of the Short Names is an active process done by the OS, which means that
a. This must be switched On;
b. The Short Names must be (re)generated out of the Long Names when the setting has been set to Off before.
Solution :
1.
Open a Dos box (type cmd at Run from the Start Menu);
Type
disable8dot3 0followed by the Enter key.
2.
Copy your music folders from the current location to another (and back if you want).
This recreates the Short Names.

http://support.microsoft.com/kb/Q121007Do not test this for fun by means of typing disable8dot3 1 because all the Short Names will have gone in a wink, and only copying the files as described is the solution to get the Short Names back.
Important : By copying all of your files for this reason (or another) the Date Creation of the files will change to "today". I myself would never want that, because there is conveniency in keeping the original creation dates/times;
Currently I don't know of a copy means that maintains those Creation Dates, while it sure can be done (XXHighEnd herself does it with the Copy To functions). So be careful with throwing away this kind of "data" (date/time creation) or at least think about it.
May someone know a means to maintain this data, please let it know. It might even be a Windows option ...
