Back To Basic Bit Torrent

[jrzd5510]

I have been happily using BitTorrent for years.  A friend decided to get me BitTorrent Pro.  Tried to download the following:

I used to just click on the magnet link, Bit torrent would open and life was good.

 

Now, it closes Bit Torrent and gives me a message that ends with "application not found"

 

So I deleted Bit torrent pro and reinstalled the free version that always used to work and I am still having the same problem.

 

Any ideas.
