Unresolved Cannot Mod Forza 4

Hi. I have downloaded 360Revolution in the correct way. It is an up to date version, and has loads of games to mod on it. The trouble is, I am desperate to mod Forza 4, I have extracted the Forza Profile and saved it, but when I go to open it, a notice comes up saying 'This file cannot be modded' Please help!!! :dash2:

 

Btw, sorry to double post, but if this helps, it is version 2.71, and don't tell me FM4 cannot be modded on 360Rev because there are countless videos where people have done it. If, however, I cannot mod the game, please can you tell me where I can get my game save modded. I only want to increase my credits and I am an offline player. Thank you.

 

I'm doing a Tutorial on this today, I'll add my Starter Save to it.

1 Race done and Modded to 99 Million Credits.

 

Would this be usable on a online profile or wouldn't you recommend it

 

I'm not sure as I Modded it and used the Save on my RGH.

Try it on a Dummy Profile online and Gift Cars etc to your Legit Profile!
