Chinese, Korean, Japanese, the specific language does not matter, Korean in this situation, some Asian characters open blank, I am working on the assumption these characters are not just scanned in. I have tried both installing the specific language suppport for the Asian language (for reader 9.3.4) and also just opening the document with admin rights does not work either. Updating to standard or professional works, but is not the preferred solution. Updating the version of Reader through a patch is not really an option.
Forgot to mention, Windows XP, SP3.
