It is a fix but it isn't a good fix. Foxit is a great alternative to Adobe Reader, I have it on my laptop as well as I had to use it when I found Adobe Reader had stopped working, for unrelated reasons, eons ago.
My point is that something is broken in your set up and all you've done is use the simplest of work arounds: a replacement program. That is a crude solution because whatever the problem is it is still there.
