Unable to access any Nexon website.

Just curious if you have maple.exe, maplepatcher, and hackshield all as exceptions from your DEP (data execution prevention)? Also make sure your
fire wall is opening up for it... I know those are obvious but you have to start somewhere.

Do you get any error from windows at all when trying to run launcher.exe? Like "windows has shut this program down" type things?

No errors, the process just starts up and nothing happens afterwards. This also affects DFO along with any website on Nexon's servers.
I've left the process going for a half hour or so, and nothing happened during that time.
