Here are the steps that I would recommend to troubleshoot. (This same principle applies to troubleshooting all mods)

First(1): Load Attila Mod manager and ensure that the mod is enabled. (Click the check box)

Step(2): Load Attila and start a custom battle. Take note of unit Melee Attack from Rank 0 to Rank 9, if it only increases by 9 then the mod is not running. If it increases by greater than 9, the mod is working.

Step(3): If you notice that the mod isn't working after this test. Disable all other mods and only enable this mod. Repeat the test with custom battle as you did in Step 2. Do you now see great then 9 melee attack increase from a Rank 9 unit?

-If yes:
Start enabling mods until your Step 2 test fails.

**Then take note of which mod is causing issues and report that to both my thread and to the mod that is causing issue's thread. This will help us know about compatibility so that we can make a note for future users.

-If no: (Which is very unlikely,)
Re-download the mod and try again from the top.
