Hi,
first thanks you for purchasing Enterprise version, and sorry for delay for answer (I were on holidays).
About your problem, please first try a 301 redirect as follow:
From URL: /index.php\?option=com_content&view=section&id=4&Itemid=37
To URL - http://{siteurl}/index.php?option=com_comprofiler&task=userprofile&user=81
Note that you need to escape the question mark (\?). About the internal redirect, we have found a problem with some URL related to components (while this should work without problems with articles as in your case). We are working to fix the problem. A solution will be available in a few days (otherwise we will refund all the users).
I apologize for the inconvenient.
Regards,
Luigi
