Maya is still down

My home copy of Maya is still down. I am awaiting a response from Autodesk.
Some are related to Mental Ray, which is missing from the newer version, so I have tried reinstalling the latest 2015 service pack, and the Mentalray installer, but nothing has solved the issues yet.
The error in the command window is:
// Error: Unable to dynamically load : ModelUISlice.dll
