The file type "Binary" is the type of file that is used to open and close and view and edit that file and is set by the maker of the file and Binary is a safe downlaod file and changing it could corrupt your files so they don't work.

Here is a simple fix I found that worked for me.

1) Clear your download history 2) Go to Options > Options > General Tab: Change your download location to something other than what you currently have it set at. Apply the changes. 3) Go back into the Options and change it back to what it was or whatever you want it to be.

You should be all set from there.
