Fatal error when installing Acidfree

Hi,
I'm novice to Drupal, and not good in php, so may be doing something wrong, but to my mind everything was according to guidelines...
I've got a fatal error right after I enabled Acidfree in Administer-Modules page:

Notice: Undefined index: aberdeen in z:\home\mysite\www\includes\theme.inc on line 45
Fatal error: main() [function.require]: Failed opening required 'modules/acidfree\views_acidfree.inc' (include_path='/usr/local/php/PEAR') in z:\home\mysite\www\modules\acidfree\acidfree.module on line 2662

I tried looking through the code, but do not understand what is the problem. Think that it is connected with themes, but I'm using only one my own theme, which is modified Bluebreeze, and other modules have no problem with it...
