I would be very grateful for any help I might receive.
When I was asked to download a PDF from the British Government website a prompt came up saying an upgrade was available for Adobe reader 9.0, as i was busy I declined the upgrade and sought to down load the form. However the form would not down load. After a couple of attempts I presumed that perhaps I did need the upgrade, so I clicked on the link for the upgrade and followed the instructions. It all seemed to go OK, but when I sought to shut down, a pop up told me it hadn't all gone well, as I was in a rush I just switched off.
When I next switched on I got a pop up titled 'osd 'with an exclamation mark in a red triangle with the word LAG beside it. I could either click OK or x, I clicked x and just carried on as normal.
This morning I have just tried to open a pdf and cannot find reader anywhere on the computer. I am using vista with service pack 1.
I suppose I could just try to download reader again but am rather wary of doing so, just in case it piles further problems on top. Is it possible that my anti-virus (avira) might have given problems with the upgrade? I don't remember if I had the anti-virus when I originally downloaded reader.
