I think I have some of my problem resolved. I found a direct link to Adobe X which also installed a patch. I also chose the option to always open in unprotected mode (whatever horrors that might entail) and I can now open files on the web. Now if I can just get my distiller to work again. The link I found on this webiste in another question was:
I had the same problem with Adobe X that when I openened pdf files I would have either a grey screen blank page or black writing grey screen.
In PDF manuals some of the pictures would be greyed out. Web pages were ok. Turning protection mode of didnt work. I uninstaled Adobe X & reinstalled Adobe Reader 9.4 updated to 9.4.2 & eveything is back to normal. So there might be a bug in Adobe X.
I'm using windows 7, 32 bit.
Hope this helps.
