That's not a typical error to see here. Have you tried running a recover on your file? Maybe this is an indication that your file is damaged.
I tried to recover my file, but the result was the same. What is more, I do get report overview page, but the rest of the report is empty.
Is this maybe fault of some damage layouts? This window pops up exactly 3 times.
Very possibly. Make some copies of your files and remove half of the layouts from one. Run you DDR on it and see if it generates the same error. If it does, remove half of the remaining layouts and try again. If it does not, start again with a new copy and remove only half of the layouts that removed previously and run another DDR. Continue this pattern and see if you can narrow this down to a specific layout or group of layouts.
This is what I wanted to avoid, but probably the only way.
Thanks for answer.
