The editor program says that it does not see system drives so that it does not accidentally format a system drive, but for some reason it is showing my system drives in the little drop down window. 
Windows XP "WMI" and "SCRIPTING HOST" configuration error.
1: Bad Windows XP install, ( over tweaked or badly installed )
2: Mis configured Windows install. ( WMI/SCRIPTING HOST configuration problem / missing components )
3: MPC-EDITOR running under a user with restricted system component access privileges.
4: MPC-EDITOR not configured to be able to access all system components that require administrative level clearance in order to RUN.
5: Corrupted Windows Storage Class entries. ( pretty common )
6: Windows XP Removable Storage Manager Snap-In not enabled in the services control management pages.
Typical Windows XP stuff.
Contacted the MPC-EDITOR programmer at MIDICASE ?
