I am using IE8 on a new laptop with Win 7 Home Premium 64-bit. I am having a problem with some webpages not displaying (whether I click on them or open in a new tab). I think this is related, in part, to a pdf problem, but I'm not sure. MOST of the pages I am trying to open are pdf, but not all of them. I'll explain how I came to this conclusion: I tried in install Adobe Acrobat 7 on my new maching (Dell Inspiron) and I couldn't install the whole program because there was no upgrade for Win 7. So then I downloaded something called PDF995. I actually paid for it, but it wasn't much (much less than Adobe Acrobat). Then I uninstalled Adobe Acrobat 7. For whatever reason now, I am having the above problem. In particular, I can't open my iStatements on my online banking anymore. Nor can I open any links on a site called NephCure.org under Research (articles) or this page: http://www.navpress.com/uploadedFiles/15074 BRP.dj.pdf. I think all these are pdfs. But there are some that I don't think are pdf. And I have been able to open SOME pdf links, so it's not consistent. Any ideas???? Anyway, in case this helps, when I print one of the webpages with the error message, here's what prints on the bottom of the page: res/ieframe.dll.dnserror.htm, in case that helps. I am able to make pdf files and open ones that I made, so that's not a problem. This is really hindering so I hope you can help. Thank you so much!
