i just downloaded the 767 and when i tryed to set up the aircraft an error message came up. it took me that in order to run the program i needed the SERVICE UPDATE 4 pack. in the first place....what is it....and second were came i get it. any help would be great. thanks to any one how could take the time and explain this to me.

HiService u/d 3 is to be applied to the 767 itself. The update is available from the d/l section of the LDS web site - http://www.leveldsim.com/sevensix_downloads.aspBud

A further note:Make sure the SP3 from Level-D is installed prior to installing FS2Crew.That is a requirement.Cheers,Bryan
