Thanks for letting me know. I tested the download but I didn't actually test running the mod from the download, so I apparently missed some things. The omission of maps2 was just an oversight.
As for warble, warble_fs1.vp contains the retail-quality music, while mv_fsport_music.vp contains the high-quality versions of that music. Not the remixes, the actual high quality master recordings. However, it doesn't contain all of them, so warble_fs1_supplemental.vp contains the retail-quality versions of the tracks that aren't in mv_fsport_music.vp.
I've fixed the Installer file, so everything should now be up to date.
