FS 2004 ground scenery problem

Dear friends,I am a FS fun and I am facing a problem in FS 2004 that I have not the knowledge in order to solve it.I have attached a jpg with the airport of Mitilini-Greece (Odysseas Elytis}.As you can see there is a problem with sea textures mixed in ground scenery.Is there any program that could help me solve the problem?I downloaded Ground2K4 but I cannot understand how to use it.In fact I do not know how scenery works in FS 2004.I have repainted many aircrafts and uploaded them to the internet but as long as scenery is concerned I'a a complete idiot.I would very much appreciate any help.You could go to Odysseas Elytis airport,in Mitilini-Greece to see the problem for yourself. Thanks a lot Apo Athens-Greecehttp://forums.avsim.net/user_files/51307.jpg
