I'm sorry but it didn't work.<br>
<br>
I have reinstalled the addon but it didn't work, reinstalled GRASS
6.4 and neither, then installed GRASS7 again, and appears this
message:<br>

Thank you for your time.<br>

Anyone has a clue about what it could be happening?
I'm using GRASS 6.4.4 in Xubuntu 14.04.

I have backported some fixes from GRASS 7 to the addon in GRASS 6.
Please reinstall the addon with g.extension and try again.

<pre wrap="">
No, GRASS 6 and 7 can happily live together.
Please let us know if the updated Addon runs ok for you.
