Apologies if this is dealt with elsewhere - if someone can point me in the right direction I would be grateful.

I have FS2004 and at various times have installed and removed various expansion packs. Having not used it recently I came back to it today, on trying to install another expansion pack, (Justflights Vulcan) and find that I can't actually start the programme. Disc 4 goes in, the FS2004 intro screen comes up - and then the following error message:

The version of FS2004 detected is not compatible with this version of FSUIPC. It is build 9.01.40901. You need the correct version of FS2004.

Check the Help-About: the build should be 9.00.30612.

FS2004 will terminate when you select OK.

The programme wont start at all.

What is happening here? It does not make sense to me at all.
