Did you copy the cargo aircrafts as well? If so, that's probably because the goods defined in the aircrafts are not available in pak128.Japan. Copy only the p****enger aircrafts, or edit the goods types of these cargo aircrafts.
Is it possible to copy airport files from another 128 pak and use in pak128.japan? I tried to copy the airports pak from pak128, which worked, but when I tried to copy airplane vehicles I would get an error message.
