In the end in the only trainer that would work with that version was L.A. Noire v1.1.2406.1 Plus 4 Trainer made by this chinese guy that i found from another site. The other trainers out there didn't work unforunatly.
Kind of weird, as the is the first time in that a CH trainer didn't work for me and i had to look elsewhere. I'm sure this is exception to the rule it think, going by their track record.
BTW, it's the retail version. Just updated, but none of the previous versions worked either. Win 7, 32-bit with AV & firewall disabled and running all in admin
@Bekim: It worked fine previously, but when I started the game up today, the Social Club UI thing appeared forcing me to restart the game for an update and everything stopped working or started crashing the game, even if in the bottom corner it claims to still be the same version. Give it a few days and CH will probably take a look at this.

I have the GreenManGaming version which is just the retail version of the game. 1.2 update breaks the trainer, nothing works. The latest trainer CH has is for 1.0 which is not the collector's edition (i think).
