OK, since your new ENW instance is fine (i.e. given that there are WLA collections taking place here), then the next thing to try and eliminate is corruption in the "providers.xml" files.  If you delete these, they will be recreated when restarting the Performance Manager GUI.  So try renaming the "providers.xml" files in each of the archives folder of each ENW instance (as specified in the "archives location" parameter in the ENW.ini files).  Then restart the the Performance Manager GUI and see if the issue is resolved.  If the problem persists, then I recommend raising a service request with EMC support at that point.  An investigation such as this could become inefficient over a forum thread.  Kind Regards, Louie Cavaliere. EMC Global Services.
