Hello everyone. I am Kashif Raza from Pakistan. Since a few day i am facing a problem with PDF files. After downloading the file when i open it it gives me the error "There was an error opening this document. The file damaged and could not be repaired". I used many PDF reader softwares but all in vain. Now i am usin Adobe Acrobat Reader. (Sorry about my English as it is not my Mother or National Language).
