imdb don't load movies

I run windows xppro and my xbmc version is 10.1 skin Aeon Nox..
I have it at least a year and imdb worked perfectly but know when
I try to load movie information with imdb it asks me again for the title!
it does it also for older files!
For know i use themoviedb!

is there something i can do?
is my version old?
should i wait for imdb addon update?


Thanks in advance for any help!
