*MASSIVE* Problem with Report Designer

Hey folks,

I have a massive problem with one of my workflows. It's a big one and at the end of it is a Data to Report node. I also created a very complex report, which outputs a fancy excel sheet.

After some minor changes to my workflow I cannot open BIRT anymore. All I can see is the "Operation in progress..." window.

After retrying 968 times and having at least 27 near-death experiences I decided to delete the Data to Report node as well as the Report Designer files in the workspace. Same problem. I then created a brand new KNIME installation and imported only this workflow. Same problem.

Any ideas? Help is really appreciated!


Maybe your PC runs out of memory? A common issue with knime.


Stupid question: Is it executing the workflow in the background?
