Odd IMDB issue

I can no longer get any info for my movies in XBMC, i ran debug and checked the logs and when I found the part where it searches for the film the URL is wrong, for example:
It tries to parse http://akas.imdb.com/find?s=tt;q=film_title
If I try pasting that into a web browser it returns an IMDB search page asking for search input. I replaced the title of the film for generalisation's sake as it happens regardless of the film, even ones I've already added to my library if I try and refresh them.
So I tried removing the s=tt bit and now it produces expected results, why is this suddenly happening when I haven't changed a single setting since I last opened it? :\

Any ideas would be great thanks
