air hauler

Hi All
Not to sure if this is the right place but since Air Hauler is a add-on i hope i have the right place... i have a couple of questions if anyone is able to answer them...
1st i cannot get the weather to work with AH even if i click the buttons with Ah i still have to go to FSX and change it to real weather is this normal?
The other point is if i take on a mission with about 10 hours to go and then do 4 hours of flying and then save it and go back to it 2 or 3 days later land ok will the real time of Ah say that i have missed the deadline ever low the in flight clock will say i have lots of time left????
Any help would be great man thanks
