Captains,I have been enjoying my NGX for months now, with about 100 hours of time on it. However, every time, for whatever reason, I have to re install my Delta Livery by PMDG, the hours left until maintenance is required is reset. This does not give me a chance to experience the maintenance feature, as 250 hours takes me a long time to accumulate. I know there are some posts about this already, but no clear answer exists. What can be done?Thanks,Morgan Wiley
