I've been having a simlar problem and it doesn't appear there are any items in the KB related to this or an upgrade/hotfix. Here's the issue. I install ADR 2012 and the program works fine for a while. Then out of the blue I get an error message saying "There was a problem displaying the file". This is not a problem that is unique to ADR 2012. I had the exact same problem with ADR 2011. And the problem there originally started with the same error message given by the originator of this post. You might ask when I've put up with this for so long and quite honestly I would say that Autodesk's service is so good I expected to see a fix quickly since I didn't think I was the only one experiencing this issue. The fact is that all I have to do is uninstall ADR 2012, reboot my computer, and reinstall ADR 2012 and it works fine for a few days. Then the problem reappears. And once the problem reappears there is nothing that can be done but to uninstall, reboot, and reinstall. I've tried doing a repair and that doesn't work. I've tried reinstalling over the current installation and that doesn't workd. The only thing that works is uninstall, reboot, and reinstall... uninstall, reboot, and reinstall... uninstall, reboot, and reinstall... Can you feel my frustration? Excuse me while I go uninstall, reboot, and reinstall...
