Uninstall vqmod don´t work

Hi,
Could somebody help me with this:
I have installed vqmod a few weeks ago and it have worked fine, but now when i try to delete or rename one of the xml mod files then my shop don´t work anymore. It is the file hide_atc_for_out_of_stock.xml
So i have to use all of the xml mod even when i don´t need some of them anymore. I also tried to delete the files in the vqcache but it did not help so i had to restore the files from my back up.
Best wishes
