Posted this on Atari Forums, seems it didnt shed light:
Alright, i finally put my TDU Disc back in after a couple of months, i played it a couple months ago, it was working fine. Today i put it in and it loaded to my online profile and everything. I then clicked on start game and then it went to the screen with the cars [once you click start game or w/e] it would load i then tried to alt tab and cntrl alt delete but it wouldnt work. I deleted the radial.cdb but there is another file just called radial.
I played TDU for a year, but cant see to figure out the problem now.
Drivers are up to date.
I will offer anything if you help me with this, even maybe RL money or cars in the game[ I do have most of the "Rare" Cars]
Thanks.
