Hello,I've have just installed FSX yesterday, downloaded the fsuipc4 for FSX. I already own the FS2004 registered version of fsuipc and use it in FS2004. When I go to register the new FSX version I put in FSX, it won't accept my registration key. Do I need to purchase the FSX version in order to get a new registration number for the FSX version??? Paul

PaulFSUIPC for FS9 and FSUIPC 4 for FSX are separate programs and you need a new (paid) licence for the FSX version.See Pete Dowson's forum on simflight. :( RegardsPeterH

Thanks much Peter! Paul
