RM Studio 8.2: Cannot open Processes anymore

Hey there,

I used to model in the traditional way with Rapid Miner and now I tried out auto-modelling but after my fifth iteration of putting a new dataset into Rapid miner and automodelling it I cannot open the process behind anymore or any process in general. It is that bad that I cannot even use the log file operator because no operator works.

When I want to open a new process there is a small process bar in the bottom right but then nothing happens.

It also said that it failed to import a lot of operators after the last update.

It was a message with a lot of red lines.

How can I solve this problem?

For some reason, Auto Model works but nothing else besides this.

I attach a screen shot. 

Thank you very much for your support!
