autocad lt 2012.... command unknown... object snap

[Penry79]

Bye to all,
It is so much that I am written but I think it is the first argument that I open, I hope I did not make a clone (I tried but did not find) and to have written in the right section.
Anyway... we come to the problem

any command of "snap object" (parallel, center, intersection etc.) that select, the command bar always signals the same error

"_par command unknown "par". press f1 for the guide. "
"_endp command unknown "endp". press f1 for the guide. "

etc.
etc.

I have already reinstalled and repaired with the cd but the error always comes.... help that I can do?

those that click are the 'key words' to set the osnap and should be recalled during the execution of a command!
then, first run the command (line example), and then at the request to select a point recall those ways of osnap.

....sorry... It's true that I've been handing over to autocad just recently after a couple of years... but I didn't think I was so bad!!!! Thank you so much!!! !
