Don't have code::blocks folder in it.. ;o
it's a problem? i already re-installed Code::Blocks, it's necessary to format my pc? ;/
That would most likely fix the problem, but would be a little bit overdone.
The folder "\documents and settings\<your username>\application data\codeblocks" surely exists, but might be named a little different.
I see that you are using portuguese as your system language, it is most likely in prtuguese and not in english and it exists on the system-drive.
That is in most cases the drive "c:", but might also be another drive-name.
If you do not find it, you can try to search for "default.conf", that's the name of C::B's config-file. It should be in a directory called codeblocks.
