I keep receiving ubd.exe errors on boot up with Windows 10. Procedure Entry Points "mmcs_get_items" and "block_object_assign" are missing and consequently Photo Stream no longer works. Please help.

mmcs_get_items is missing from ubd_main.dll and block_object_assign is missing from ubiquity.dll

How do I fix this?
