After installing Zoho Assist unattended access ; I successfully tested; but quickly after installing the client the login screen has gone black, and I am unable to wake it up or pass credentials via Zoho Unattended Access or even via the local keyboard.   This happened pretty much immediately after adding Zoho Unattended service to the server. 

Server 2012 R2 is the OS.  Any known issues that have some workarounds/resolutions I can try.   I hate to have to remove the product as it seems very promising but I cannot constantly be rebooting my server because Zoho nerfs my ability to login to the server at all.

I will be making the multi hour drive in the next few days to access the server on site and get it fixed up and will have to remove Zoho unless there is a fix available.   This seems to me like it would likely be a rather common issue/bug with the product.

Appreciate any information that might help resolve this.
