Digg Digg Broken since upgrade to v5.3.0

Hi,

I’ve upgraded from the old version (which was working fine) to the new
version where the toolbar buttons don’t display properly as you can see at:

sk-sequence-cannot-be-run-because-the-program-files-for-cannot-be-located-on

Can you please tell me how to fix this or downgrade to the old version?

Many thanks,
Cliff
