Hi. I have a new HP laptop. It uses Windows 7. I have Adobe Reader -- I had 9.0 and was having problems so took it back to the store and they have now loaded 9.3. It is hit or miss on opening some pdfs. The only error message I get is that "there is a problem with Adobe Acrobat Reader. Please try again. I am not technically oriented, and this is very frustrating. I tried to call Adobe and they said that I need to work off of this forum.
