For anyone who has Windows Vista or Windows 7 find the NWN folder and right click on nwmain.exe and select the compatibility tab. Then select Run As Windows XP SP3. Do the same for nwlauncher.exe, nwn.exe, nwupdate.exe and if you have it, xnwnconnector.exe which are all in the same folder.
That might resolve the issue for access the game.
If the game loads a screen and then gives you compatibility errors you may need to do a critical rebuild.
Critical Rebuild Download on NWVault.
If that still doesn’t work, uninstall everything and reinstall.
