Having uninstalled and reinstalled the acceleration pack one two many times when the product key is entered you can not activate it via internet says by phone or activate later. Cannot activate by phone get error message product code not found. Bullit activate later game starts. Called Microsoft support and they said they did not have anymore product keys for FSX it is no longer supported thru them. Question, check activate later start program everytime seems to be a pain and it says you will not get full use of the features. Is there anyway around this? I have already ordered a new copy of the program seems like a waste. Anyone run into this?
