IM new to flight simming and only know computer basics...Ive run FS2004 for a few weeks and have had no problems..When I tried to add on PMDG 737NG I got the following message: The version of fs2004 detected is not compatible with this version of FSUIPC. It is build 9.01.40901...You need correct version of fs2004. Check the help-About. The build should be 9.00.30612.FSUIPC will terminate when you select ok Can anyone tell me what this means and what I need to do ? Thanks Chris S.

What version of FS2004 are you using? Did you upgrade it? Had some problems as well before I got the FS9 upgrade...Peter

You need an updated version of FSUIPC, version 3.75 from here:http://www.schiratti.com/dowson.htmlDownload it a move the fsuipc.dll in this download to your FS9modules folder after renaming the older FSUIPC.dll to XFSUIPC.xxx. This will allow your updated FS9 to (version 9.01) to run with it.
