Cookifier 0.6.1 and onwards on NPP 6.1.3 doesn't allow to type cyrillic letters, like here: http://sourceforge.net/projects/notepad-plus/forums/forum/331754/topic/1959136/index/page/1 . 0.6, 0.5.4 work okay.
did you try version 0.7.3?
So if your bug report is NOT a duplicate of this one:
.. then can you describe what happens when typing cyrillic letters?
Yes, it's a duplicate, I think. I was dealing with the same bug, but with a czech keys. Workarround with unchecking the option "Go to defintion by pressing ctrl + left mousebutton" helps me in version 0.7.2. In the version 0.7.3 the bug is fixed. But version 0.7.3 isn't in Notepad++ plugin repository yet, so I have to download the plugin from here and installated it manualy.
Meanwhile the Pluginmanager updates SC to 0.7.3.
I changed the version for the Pluginmanager long time ago,
but only the owner of that plugin can accept it in the end.
