So I fixed the cyrillic text in the menu by using
Microsoft's applocale utility. I didn't want to change the standard language for all non-unicode applications to Russian.
It looks fine now, but the new kinopoisk scripts are still not working for me. I get
this in the status bar when I try, and then nothing happens.
I downloaded the old kinopoiskposter.dll plugin from an older release, and this version seems to
work fine.
edit: I just tried setting Russian as the standard language for non-unicode applications globally in the windows regional setting to see if that would fix the new version of the script, but it didn't.
I'm running the x64 version of vista. Is anyone else having similar issues?
