Hi
Despite a number of attempts to solve an issue with the 757 base package I Now come here to find a solution.
Basically I have re installed the base package which does so successfully but when I try to load the aircraft from the start up p3d screen I get a CTD? 
No other issues with any other aircraft loading and yes I have turned off Antivirus and Firewall.
I have had this working before without any problems but not since a re install.
