Update (12/01/2015): Version 22.214.171.124 fixed the issues referenced below. The version that’s current at the time of this update is version 126.96.36.199.
The SQL Server Engineering Team recently acknowledged that there’s an issue with the recently released SQL MP version 188.8.131.52, and have issued a temporary workaround for the issue here: http://blogs.msdn.com/b/sqlreleaseservices/archive/2015/10/16/released-system-center-management-pack-for-sql-server-and-replication-6-6-2-0.aspx.
If you’ve already downloaded this MP version and are seeing this issue in your environment, you are advised to apply the workaround published above. If however, you’d rather revert to the previous MP Version (SQL MP 184.108.40.206), you can get that from the download center here: http://social.technet.microsoft.com/wiki/contents/articles/16174.microsoft-management-packs.aspx?PageIndex=6
