I get the following message every time I try an open some of my saved PDF files in Adobe Reader 9
"there was an error opening this document. the root object is missing or invalid."
these files are not down loaded from a website, they are files I greated some time back and I have not opened in a while.
I am runing window XP and this dos not happen with all my PDF files.
can you help.
Sounds like the files are corrupt. Time to restore them from a good backup.
