Something has changed in my Rc4 as, initially, I could save partly flown flights using the Ctl-Shift-; and recover them OK using the "Load Previously Saved RCDs" button. However, whilst the one saved in Flight Sim loads fine when I go into Rc4 and try to load it I get an immediate CTD - MS report window shows the cause as something like "ai.dll". I then revert to the last Rc4 autosave entry and it loads OK, Stange. Any ideas and thanks in anticipation.:-(
