Civ4Col Modder
Which Victory Types did you select when starting the game?Can't start revolution.
(Game Options Screen will show you. I think it is F11, but there is also a button at the top of the Main Interface.)
If you do not select Victory Type "Revolution" starting the revolution is also not possible.
That is not a bug, that is how Civ4Col has always been since Vanilla.
----
Otherwise I know for sure that in last public Release 3.0.1 starting revolution is generally possible, since we had game report from Revolution.
(Also I can hardly imagine any bug we could have implemented preventing Revolution.)
----
Most likely explanations:
1) You selected the wrong Victory Types when you started the game --> Game Options Screen
B) You do not yet have enough Revolutionary Points in general --> Revolutionary Advisor
----
Please show Screenshots for both of these.

If none of my explanations is correct, we may analyze the save.
