In order to work as advertised, CSN HAS to be installed in the same path where you installed Crysis Wars. You can do so by choosing Custom installation and providing CSN with the location of the game folder when asked - that's all. Just keep in mind that the CSN download link always contains the latest version of the client (now 1003). Former versions will not work. Also, installing the game and then directly the 1.5 patch is all that's needed before installing CSN - no 1.3 patch or earlier versions are needed. Also, make sure you DO NOT have any third party mod, connect tool, or patches already installed or CSN may not load/work correctly. For instance, many players tried germancrysis patch, which once installed will prevent CSN to work properly. That patch cannot simply be removed because it modifies the game files - the only way to get rid of it is to reinstall the game. If something went wrong to keep tinkering will only create more issues. The safest way to proceed is uninstalling Crysis Wars, its patch and CSN and reinstall the game, the patch 1.5 and CSN (giving the installer the game correct path) in that order.
