F1 2012: Engine sound replacement V10, V6, V12 and classic V8

Hello all, this was just a simple test to see if I could get what I've always wanted in f1 2012: V10 engine sound.

what I did to get these engine sounds was very simple. I bought f1 2013:classic edition. so I have all of the engine's .bdl files.
so I copied each of these:
classic_v10_30.bdl
classic_v6_15_v3.bdl
classic_f12_30.bdl
classic_v8_35.bdl
from here:
K:\Program Files (x86)\steam\SteamApps\common\f12013\audio\bundles
to here
C:\Program Files (x86)\Steam\SteamApps\common\f1 2012\audio\bundles
and as I was driving a Ferrari I simply backed up the original and then renamed each of these .bdl files to ferrari_12.bdl (individually not all at once!)
the results are seen in this video.
Now for some reason these sounds have only worked for me so far in the Time Trial game mode as seen in the video.
If I try to use any of these sounds in the career mode the game crashes. . . this procedure does make the game very unstable.
I'm looking for more experienced f1 2012 modders out there to help me to get these sounds to work in all game modes, because lets face it, these sounds are much much nicer than today's V8s :D
