I found a trainer that actually works decently in the meantime, albeit I'm only using the 'freeze timer' and 'no penalty' option. So I can't say if all of the other options do work, but it's better than nothing. The trainer AND the game works flawlessly with each other. No crash after 2-4 hours of playing. Even longer in total.
It's called MT-X, Mega Trainer - eXperience. Google it.
I have 22.214.171.124 steam version running on 32b win 7. The problem is that promo trainer with 1 bounty add option is working fine but when i downloaded the original version with all options game is crashing to desktop. (i tried all from troubleshooting section and more).
I am experiencing the same issue running the 1.5.0 Retail+eadm trainer with need for speed. This is what i got from the event log: Problem signature: P1: nshp-xxxxxxxx.exe P2: 0.0.0.0 P3: 4dc6bc03 P4: URLMON.dll P5: 10.0.9200.16660 P6: 51f1c5f7 P7: c0000005 P8: 000856c0
Faulting module name: URLMON.dll, version: 10.0.9200.16660, time stamp: 0x51f1c5f7 Exception code: 0xc0000005 Fault offset: 0x000856c0 Faulting process id: 0x1528
Currently running windows 8. Trying to find a fix myself. IF you have IE 10 i would try reverting back to 9 and then retry the trainer (www.cheathappens.com/show_board2.asp?headID=114676&titleID=13673).
