"task could not be loaded" error EG 5.1

[khunter]

Using EG 5.1. I am able to use Query Builder and Filter & Sort, but trying to create any other Task (Summary Tables, Graphs, Regressions, etc.) gives me the following error: "The task could not be loaded due to an unknown error."

This error is not limited to a certain project. It happens with any project I am working in.

Is this a new install of EG 5.1 and has it always behaved like this or is the case it was working OK but is now not working?

In either case I would be inclined to re-install EG 5.1 as a first step.

It was working fine, but stopped recently.

I will try the reinstall.

I get that (in 4.3) when trying to open a task for which input data set(s) have not yet been created. Are you trying to open tasks before running the entire process flow up to that point?

It doesn't sound like it, based on your description of creating new tasks, but that's my experience with that error and maybe there's something you're doing that is related (is it when you create the tasks, or when you run the tasks afterwards)? Does it matter if you run the entire process/project or if you run them one at a time?
