You need the:
be2970b0ada8e42cf891ce60ffe69575.xml
teams.csv (in the editor's main folder)
Open the be2970b0ada8e42cf891ce60ffe69575.xml file and change the "no" to "yes" of the "new" team that you want to activate, lets say team id 48 which is Cornish Pirates is the one you want to activate the line should look like this:
<team Index="48" Active="
yes" Type="england" CodeId="ID_CORNISH_PIRATES" FeGroup="
european" StringTableId="
2102" TeamName="Cornish Pirates" Abbreviation="CPR" HomeColour="12,36,137,255" AwayColour="117,191,225,255" Logo="corn" />
Bolded=new changes
* FeGroup - is the group that the team will be in ie. european, super14 ect... **Note! there can only be 30 teams in a FeGroup, if there is more then 30 the game will crash.
* StringTableId - is the name of the team that must be in the .english file
* Logo - the code of the logo is important when you want to make mini-kits and ingame logos for the team, if you are going to make a mini-kit for this team the "corn" part must be in the mini-kit .fsh file otherwise the mini-kit won't appear correct.In other words the logo code pairs the mini-kits and ingame logos with the team id.
Once you have that done and sorted you will have to edited the teams.csv file in the roster editors main folder, open it with notepad and go to team no. 48 and change it to look like this:
48,yes,england,Cornish Pirates
save and exit.Open the roster editor(the old editor works the best for this) and you'll see that the team that you just activated in in the "england" club selection, click on the "new" team and you will either see that the team has a few players in it or none at all and you might get an error, if you get an error just ignore it.
Now fill the new team with players until its full and save.
Here it is explained a little bit better:

Here is also some useful info:

Once that is sorted you'll just have to use filemon to get the new team's mini-kits, kits, logos, ball ect...
And also the logo that appears in the "squad management" screen must be added into the b33c1afcdd66fdde967cdf5a799f00e7.fsh file.
Okay I hope that this will help so long, will post the new filenames of the new teams that I've activated so far later on this thread.
Cheers
