I have to prove I own the game in my library before I can play it ...!
I went to play this game recently . Had to reinstall because I had not played since I updated my PC .I found I could not play because suddenly the key was already in use wtf. so contact ubsoft and this was the reply I got :
Carlos B @ Ubisoft Support
wonder if it will ever happen. this is the only game that I can not play due to stupid stuff like that. my other games run from steam just fine. wonder if we all can complain to steam and have it fixed?
*POSSIBLY OUTDATED, MAY STILL WORK, MAY NOT* *Uplay Crash Fix* how to be able to launch From Dust through steam no fail !
i worked it out, do the following step, i'll make a video if people so desire
*UPDATE3* Ubisoft have since released a newer version of UPLAY which has a different layout from the video, the general idea of this fix supposedly still works, but the buttons...
