I disallowed the other FSPort campaigns if you have the ST:R mod active. You can get them back easily enough; just launch FSPort or FSPort-MediaVPs.
The campaigns are compatible with each other, but we made ST:R a separate mod because we overwrote the FS1 persona voices. If you were to play through the FS1 campaign with ST:R active, you would have in-game messages with FS1 voices but persona messages with ST:R voices.
(That being said, it might be possible to re-engineer the voice package so that the new voices would add to, rather than replace, the FS1 voices. This would require a bit of investigation.)
