I hear the Intro video music, but no movie shows. Sometimes I also can not get into the User Interface - the parachute icon shows, but I need to press CTRL+ALT+DEL to close the program. What is wrong?
You might have installed a 3rd party video codec packages. They can cause all possible issues and problems. For example, the K-Lite video codec package is known to cause problems with Falcon 4.0 Allied Force. If you have this installed, do the following:
Open Klite Codec pack > Configuration > Fddshow > Video decoder configuration and change the MP42 format entry to disabled by clicking on libavcodec.
As a result the standard MS codec will play the AVI movies and FDDshow is not used for this type. Falcon will run fine with movies then.
