I bought Active Sky XP through SimMarket and I installed it with no problem. I then clicked it twice and got to the account creation part and I entered all the fields. I entered the license key and I didn't no what to put for the License Order Id because SimMarket doesn't give one, so I put the order number. I then enter the rest of the fields and then checked the two boxes and pressed ok and then I got license key invalid. I tried copy and paste and manually entering numorous times and it didn't work. I have a total of three email, so I tried to change the password and nothing worked. Why is the license key invalid when I bought it from a reputable place.
