(does a little dance) Go me, uh huh go me! (giggles) Well i poked around on line a little and i found this.

CEP_UPDATER.ZIP ZIP 606.87Kb 14619
This has two files for Windows and two files for Linux users.
Place CEP_update and erf.exe in your NWN directory and start CEP_update for windows.
For Linux, place cepuplinux.sh and erf.linux in your NWN directory and start cepuplinux.
In this future this will be a fast way to update however since almost every model in cep has been compiled and textures compressed this will take some time for this update.
This downloads only what has changed and injects it, and makes all the changes necessary to bring a previous version up to date. It works automatically installing everything you need.
and i simply downloaded the erf.exe, and now the updater works. . .i think. . (goes and acts like she knows whats shes doing again)
