You can tail this application directly with:
ssh -t 52eeb24b500446f59000012e@<MY_APP>.rhcloud.com 'tail */log*/*'

This will probably answer your question, https://www.openshift.com/kb/kb-e1080-why-all-rhc-commands-on-windows-result-in-dl-is-deprecated-please-use-fiddle-error.

The bug is closed but I think it may need be to reopened if you're still hitting this issue. Try updating rhc first and then give it another try.
