so can anyone help me out.... or like send me a copy of their nwserver.exe?
Dude, no. The solution here is:
1. Back up all the files in your localvault, dmvault, modules directory, and just about everything else you think might be created after installation. Put these files in a different folder or drive.
2. Uninstall NWN.
3. Reinstall NWN.
4. Copy the files you backed up into their correct locations in the new install.
It may not be the quickest way, but I bet you never screw your install up again!
