PROBLEM
I have such problem since so many days as i can't download any vista themes from internet and if i download it then i can't apply it.give me solution as soon as possible.
SOLUTION
Download the vista uxtheme patcher
The error you are getting says that the theme can not be loaded because theme service is not running, so to start the themes service press WIN+R on your keyboard, type "services.msc" in the run box (without commas) and from the list that opens, find the theme service and start/enable it.
