In this article i will explain how to delete the password in a level.
first of all you need a HEX-editor: You can download it from http://www.jbrowse.com/downloads/installAXE.exe
After installing we can begin:
Start the HEXeditor and open the locked level (*.j2l).
on row 000000B0 you will see in the middle 4C.
Select the colum AFTER 4C and type 000000 (six times 0).
Now save the file, and try to open it. It will ask for a password but just click OK, and the level will open…
