As it says.
Installed the latest download version (1.3) in my two day old desktop and it won't run from the Game Menu at all, no error message.
Going to the PON Folder and clicking the .exe file gives the error message in the header ... installed twice, and made no difference. Looked at the PON folder and, lo and behold, there is a file name dx3dx9_[color="#FF0000"]37[/color].dll ... so I renamed it as dx3dx9_[color="#FF0000"]31[/color].dll and click on the menu ... and it now works.
Crazy thing is, in the OLD Desktop machine, running Windows 7, I checked and it has the dx3dx9_[color="#FF0000"]37[/color].dll, but runs OK.
I don't know whether this is a missing or misnamed file in the .zip file for the game or whether it is some weird Windows 8.1 thing (I am failrly sure that the existing file works in my Windows 8.1 Laptop).
Just thought you should know.
