To move your NotBlock-Data folder you just move it to the new location after you have closed your NotBlock and your DAW otherwise NotBlock will try to save data to the folder you just moved.
Then you have to open the textfile "C:VST-NOTBLOCK.TXT" in notes and edit the first line (do not touch the second line as it will corrupt the installation) to point to the new data-folder-path. It shuld end with a "".
Or you can delete the file "C:VST-NOTBLOCK.TXT" after you moved your data-folder and start your DAW and NotBlock plugin and enter the data-location and your Licence-code again.
