Hello R'as al Gul! Thanks for the quick reply.

I ve installed the Beta_8. The maps and castles were with the Beta_8 download ie in the same place, but separate downloads so I ve done nothing with those.They were here:

The install appears to have gone well, but theres a mixture of MTW and STW musics-the medieval bell between campaign turns. And the same Medieval choir music for battles.

The disks are the original ones I bought some years back-two for MTW and a separate expansion disk for VI to version 2.01. For MTW/VI previously I ve been using the Gold Edition which , I think was not preferred for this mod.
