command not recognized after Civil 3d SP1

[technetic]

Hi, 

I just downloaded SP1 to mi Autocad Civil 3D (spanish), but now when i try to order some objects behind others it shows "Comando BACK no reconocido..."  (Command BACK not recognized), i have tried to repaired the installation, reinstalled, unistalled and reinstalled, and the problem stills, so i guess it was the SP1 that change the language pack.

Thanks

Are you typing that command?  What happens if you use the command from the Ribbon or a Toolbar?

BACK is not a command in English version, obviously I don't know about the Spanish

I usually use right click> draw order, i didn´t try the command on the ribbon.

I reinstalled Civil 3D but not SP1 and it works fine now, but i would like to install it anyway, i think i´ll wait for a hotfix on that

THANKS

I use SPANISH version of civil 3D, and i don´t know if it occurs in other languages versions
