It looks like re-uploading the mod is more complicated than I expected.
To summarize a long story, a couple of months ago I lost all the information stored in my old VAIO laptop. As I had been working on my new laptop for almost three years, I did not worry to retrieve any RTW modding stuff.
But I forgot that all the installers for my mods (Res Gestae, 77BC, Caesar Imperator et al) were stored in that old laptop, as some sort of backup external drive. So, unless I come across some backup CD, they are all lost.
The alternatives are now to make new installers and re-upload them, which would mean losing the great installers created by Hip, including the great FRRE CD-Rom. Or somebody in this community being so kind as to upload them again from his personal files.
