KotOR tool cannot open source scripts

[Exile007]

My apologies if this had been brought up before, I couldn't find it in the search function.

 

Whenever I try to open a source script in KotOR tool, it will say "Value cannot be null Parameter name : item."

 

This only happens when I select a KotOR 2 one as well.

 

Also, when I select Kotor 2 as the form I want my compile script to be, I get the same error message.

 

If anyone could help me out here I would appreciate it.

 

EDIT: I don't know what I did but it works now.
