Thanks for the answer Adrew, I'll try that.
I usually install the Mod in this order:
1) Game install
2) Patch 1.1
3) SUM v1 update
4) SUM Tatoo Fix
5) SUM v2 update
6) SUM v2.1 update
7) Save Edit Shoe Fix
8) Playmakers Plays and Sliders
9) SUM2 Roster
Here's the weird thing: everytime I install the game, it "updates" my DirectX 9.0c

, copying some files in my hard drive. I have the last DirectX 9.0c (march 2009 redistributable), so this is impossible and must be some kind of mistake. Using my previous OS (Windows XP UE7) this didn't happend, and the game didn't crash at all. Any clue?
PD: Sorry for my english, I'm from Argentina.
