I take it you are using a very old version of FastActivate, since the recent versions do NOT have servers attached to it. The old version had 4 buttons (the 1st one used to be for updating the Meta.txt), whereas the recent versions only have 3 buttons. Therefore, use only the LATEST version of FastActivate.
Run FastActivate.exe from the root of the device. Alternatively, you can run it from inside the map folder and place the meta.txt file in the map folder as well.
Confirm if a .dct file is being created in the new map folder. If there isn't one there, then you haven't activated the map. If there is one there, delete it and run FastActivate again.
Also, don't forget to patch your navcore with FastActivate. It's the 2nd button in the latest version.
