Custom Characters:
Vista, Windows 7 and Windows 8 or 10 have some limitations that will prevent Kaiser from operating properly. These are built in security features that are not allowing the transfer of the image through the firewall. This includes not allowing the Custom Personal Pictures to transfer to the Kaiser Server.
Here is what you need to do.
right-click on the Kaiser shortcut icon thats on the desktop, click Properties then and click the Advanced button
Check the box for "Run as administrator"

This may vary in steps depending on the version of Windows you are using as each may look different.
