Transfering FS9 Airport to FSX

Hi,im living Germany and was born in the city of Erfurt. Erfurt has a nice little international airport. http://www.flughafen-erfurt.de/de/unternehmen/unternehmen_video.htmlFor the FS9 you can find a wonderfull freeware scenery here: http://www.fslive.de/projekte.html . This one is full of details and i realy would like it BUT it is for FS9 and i use FSX. Im also using Addon Converter X for some stuff that i only found in FS9 and most of the time it works but this time there are several Probs :(1. The airport hast the wrong sice, it doesnt match the satimage of VFR Germany 4 and also the overlayed apronchart doesnt match the AFD file. 2. The Taxlines are using the texture of a railline o.o3. Problems with the mesh (irregular hills where shouldn be hills)4. and maybe othe stuffFirst question is:Is the wrong position of the Apron and its Buildngs a problem of using it in FSX or did the FSlive team somthing wrong here?PIC (the chart is positioned that it matches exactly the runway):And then i want to know how to start the moding, whats the best way for making progress? What even is the right way, what do i need?Atm i only made som AFD files using ADE. All object should be ready cause the "Erfurt 2008" scenery allready has them.In advance :Thanks for your helpMax
