I was using Bitdefender 2010 until something wrong happened to it with the vsserv.exe unavailable thus i reinstalled it and it prompted me to get 2011 version. After installing 2011 version i get "No More Files" Error message when im trying to save word,odt and pdf files. I uninstalled bitdefender 2011 and i could save files again. After reinstalling it i get the error again so i am certain it is Bitdefender causing the problem. Being able to save my work is really causing me problems hope the issue would get fixed soon.
