Manual install, even the default DC3 wont show on the airplane menu ... Tried the FS200 version C-47, same thing. I thought I remembered a reset, if you clicked yes for say gauges it didn't want to load, and you should have clicked no.
Installed C-47 FSX on FS2004 ... did not like the MDL 's Now even the oem DC3 is gone . It's in the airplane file , Just will not load, not even on the plane menu . How does one reset or un-confuse it
