Hello Peter,
I finally found a copy of Richard Lovett's Mous-As-Yoke add on for FS2004. It includes an older copy of FSUIPC which according to Richard's readme file he licensed to include with his program. I managed to get the newer version of FSUIPC installed and running with my installation of FS9 but it doesn't seem to like working with the MAY addon.
Is there a registration key I need to use this program, or is FSUIPC no longer licensed to be included with this program?
I will email you a copy of the set up file so that you can take a look and see what I am talking about if you need them. The whole set up file is just over 7Mb so I can't attatch it here. The setup uses some default locations for installing FSUIPC and MAY so you might want to be careful when installing it so that it doesn't overwrite anything on your PC.
Thanks
Thom Doonan
