Well, I've done it exactly the way it was explained. Apparently, it's still not working 

The only ssi that's working is default_night, even though this one's also a little bit glitchy I believe:

Hey guys,

I'm pretty sure that there's already a topic about this issue, however since I can't find this topic and
this lighting problem is really pi**ing me off, I just decided to create a new topic.

Basically, my whole lighting is completely fucked up. EVE...

Since I already post this error, but into another Topic ( "could not find script" ) I decided to do a new Topic.

If it counts as spam, Im sorry for it!

Screen of this error: ^

...

Any error from the console? If not you might want to try outputting a logfile.

Hmn this time the game didnt crash, but  I got this error:

Have you applied a third party patch to your mod tools installation?

No I haven't.. I guess so.. Sorry uhm how can I check that if I've applied a third party patch? :s
