Some of the cells in the grid are blackened. Fill the remaining cells with exactly 12 pentominoes. Pentominoes may be rotated and/or reflected. The given red border divides the pentominoes into two groups such that 6 pentominoes exist on the left and the remaining 6 exist on the right.
Solution code: The marked row, followed by the marked column. For each field use the letter of the pentomino. Use letter "E" for the blackened cells.

Für unsere deutsch-sprechenden Mitbürger: Es liegen sechs Pentominos auf der linken Seite der roten Linie und sechs rechts davon. Damit sollte die Lösung einfacher sein.

@Alex: Yes you have to use all 12 pentominoes e.g. no pentominoes may be duplicated.
I also apologize from the 4 puzzlers who had solved the puzzle without the additional constraint. But I think such a change was needed.

you do want us to use all 12 different pentominos, don't you?

The figure and the text of the puzzle has upgraded with an additional constraint.
