This isn't so much of a bug, as an annoyance. As the title suggests, for whatever reason, PA refuses to launch on steam no matter what i do!. In any case, just wanted to make people aware! Cheers
Wrong again did not fix. Specs are as follows FX 8350 660 TI Corsair Vengeance 1600 MHZ (8G) M5A99FX Mobo
Also i would like to add that the PA launcher will not accept my steam key (ie uberent launcher). I tried updating the drivers (for the card however physX failed because it had a higher version number than the one offered off of nvidias website. Im assuming that the next drivers will probably sort of this out
The steam installer installs the correct version. Make sure your directx9 is up to date I found that after I had a problem where you click on the PA icon in steam and nothing happened. Went into its folder location and executed it from there and a window popped up saying my dx9 version was not upto date. Try that.
