I keep getting an Error 52 whenever I try to save so I can't finish my Boot Screen. Everything else I try doesn't work either. If someone can tell me how to correct this problem please tell me.

Could be related to two files it requires in order to function: msvbvm60.dll and comctl32.ocx. I don't think Windows comes with either by default. So could try grabbing both from http://userxp.belchfire.net/indexbe.htm#How_to_install and drop into the same folder Booteditor is installed.
