Cumulus Support

I can no longer start CumuluxMX:

sudo mono CumulusMX.exe

Unhandled Exception:
System.IO.FileNotFoundException: Could not load file or assembly 'Devart.Data, Version=5.0.1181.0, Culture=neutral, PublicKeyToken=09af7300eec23701' or one of its dependencies.

This is version 3063 which has been running fine for some weeks. The only thing I did before this happened was checking packages:
sudo apt update
sudo apt list - -upgradable

But I did not upgrade anything.

Anyone know what is happening here?

Edit: reinstallation of CumulusMX.3063 solved the problem.
(I also updated all packages in Raspbian Jessie)

One of these two files must have been deleted...
Devart.Data.dll
or
Devart.Data.MySql.dll

Yes, looking in the old folder I can see Devart.Data.dll is missing. When I searched yesterday I noticed I had Devart.Data.MySql.dll and did not know it should have been two of them.

But luckily it is very easy to do a new install, rename the old folder, install new and copy over data- and web-folder pluss som config files. These files I have in several backups.

Thank you.
