Which mods section? In the Main Civ 4 folder or in your My Documents folder?
And just to make extra, extra, extra sure...after you loaded Civ 4, you went to "Advanced", Chose "Load a Mod" Selected "FexFX - Bigger & Longer (v.05)" from the listed Mods, it advised you that the game would restart. Then the game restarted, and it said "FexFX - B igger & Longer(v.05)" in the upper right hand corner of the main menu screen...and FX-Huge is not a map size and FX-Epic and FX-Grand are not speed options?
.
oh and are you using the 1.09 patch?
