I just got SP4 and now I'm having trouble with saving sessions, i go in and setup everything for a sessions, (ATLS Crossing,Trains,A.I, Etc...) Then I use the quickdrive button and save(which worked in SP3) After That i get into driver and nothing is there, I just roam aimlessly around a map void of trains. Also When I go back to where i was, all my ATLS Crossings Need Setup again, Any Help Guys?????:'(
