I'm not familiar with this Scenario and I don't see an entry for it in the Mods & Scenarios sub-forum. Is it possibly old and not updated to be compliant with 2.30h?
EDIT: Just saw your post under Rise of Mania, so I assume this is the one you are having problems with? If you took the link from the first post, then it says it is compliant with .22h, which is WAY back before BtS. So that will most certainly not work with the latest version of BtS.
In the posts above yours it says there will not be an update to .25, so that means that it is completely incompatible with BtS version of FfH.
