It is unfortunate that a big airport software producer like you, did not think about people with FS2004! Many acquired their software and it still remains in fs2004 like me because we like it and others because it doesn't have a machine to run fs x etc. it is an unnecessary investment when fs2004 meets our objectives well. on the other hand, you didn't think about these people or us that we have! it is regrettable, I will not buy more software from you!
