Finally got it to work!...but have another problem.
Dan77, you're right - my changes on the "Adjust Waypoint Altitudes, SIDs and STARs" were not being saved. I looked at my logs and it said "NOT using Adjust Waypoint Altitudes, SID..". So I just opened that the adjust waypoint altitudes page again which already had my "DP" and "ST" marker set and hit save again. No changes -just opened it again and saved it and voila, my log now said ""Using Adjust Waypoint Altitudes, SID".
Tried the flight again and this time, right before the start of STAR waypoint got the STAR clearance and the "remain on this frequency, I'll have traffic for you".
HOWEVER - the problem I am now having is that the star clearance is for the "Sierra Tango" default STAR, even though I have a different STAR name put in for all the landing runways! I have tried this both with the "STARs active" checked and unchecked, but the STAR clearance is always for the "Sierra Tango" star. Why would ATC say "Sierra Tango" when I have a different STAR name for the arrival runways (all of them!) on the SID/STARs page (and saved!). The correct SID name is being called out but not the STAR. I understand ATC calls out the SID/STAR name phonetically, but I am not even getting that.
Could it be possible that PFE ATC doesn't decide on runway until close to the airport so the start of STAR will always be Sierra Tango (and therefore not picking up my STAR name as a runway hasn't been selected by ATC yet)?
