Hi again I'm trying to open a file from a government website and I keep getting the following message internet explorer has encountered a problem with an add-on and needs to close. The following add-on was running when this problem occurred. Add on name: AcroPDF.dll Company Name: Adobe Systems Incorporated Description: Adobe PDF Browser Control I also had this problem a few weeks ago with the tipperary institute website. There is an option to learn more about add-ons in the box but my pc freezes at that point. Anyone any suggestions. I feel it might be something to do with my firewall or protection. Cheers Edel..
