VMWare Server Stats not showing after roll back to 10.2

VMWare Server Stats not showing after roll back to 10.2

We recently rolled back to 10.2 after an issue upgrading to 11.2 . The last outstanding issue I am unable to resolve is our VMWare servers are no longer statistical data for anything. It does show availability and does show all Inventory details. Also when trying to rediscover the device it display " Error!" Is there a fix for this? Please let me know what additional information you need.

VMWare versions 5.1.0 and 5.5
