Well I downloaaded lcpdfr and that had an auto installer, so that installed dsound and some other thing that it needs to.
And when I launched the game the simple native trainer worked. So the dsound asi loader works with 1.0.7.0.
I also managed to get the cruise control to work, I found out it needed another dll.
And last but not least I manged to get the lcpdfr functioning by doing what they said on the lcpdfr forum.
I can't downgrade my gta as far as I am aware because I bought the steam version of the game which comes with version 7 installed.
But that's for your help anywy, from how I look at it the rest of the mods should be plain sailing.

Ps this was sent from my blackberry.
