Afcad2 problem

Hey!I have 2 Afcad2 files for 1 single area ETSN in my FS9 situation.One Afcad AF2_ETSN is for the main airport, the other one AF2_5TSN is for the heliport within the same area. You can find the files on http://www.jive1.be/Scenery.rarThe problem is that an AI helicopter does all necessary things when it taxies from its parking place and takes off in that situation, whereas it crosses quite well the taxiway of the main airport when taxiing along its own taxiwayin direction to its own runwayBut, when turning back en flying in it lands, but does no longer cross the taxiway of the main airport but instead it turns right on and follows the taxiway of the main airport, and not its own....I had already myself been experimenting in order to find solutions, but nothing found. One of the experiments was setting 3 taxiway lines towards its parking place, bu that did not improver the result.....Who can save me this problem?GreetzJive1
