I am using Reader 9.1.3 and was trying to open this pdf: http://www.xilinx.com/support/documentation/data_sheets/ds162.pdf and got the error in this message heading. Other people have been able to open this document so I don't think the file is damaged. Any ideas?
Clear your browser's cache and try to re-download the file.
That worked! Thanks...
I tried clearing the cache. The error message went away for a while, but then came back.
