I'm not very good with computers, so maybe this is an easy fix. I used to be able to double click on a pdf file and it would open automatically in Adobe but now for some reason nothing happens and then eventually I get an error message saying that it can't connect to a DDE (or something along those lines).
I haven't made any changes to my computer at all. Since this problem started happening, I tried downloading the updates but that doesn't help at all.
This is a big pain, so any help would be great!
