[Wine] Playing Neverwinter Nights

[D4L1D4Y]

I've installed Neverwinter Nights using a wrapper in Wineskin, but when given the option to select an EXE I don't know which to pick. I've systematically gone through all the different things I think are most likely, but nothing lets me run the game. 

With some .exe files, such as nwmain.exe (which i thought would be the one) the whole Wineskin program simply stops responding. 

I apologise if the answer to this is simple, this is the first time I've attempted using Wineskin and I'm completely baffled. 

Thanks in advance.
