do the commands show up in the help files? (input section..bottom), if they don`t then you may have some problem with the install, if you ever installed the 1.13 patch before (I seem to recall you did in an earlier post a while back) then it may be that the enhanced commands you are trying to use have expired, if thats the case then you can`t just re-install, it`s either the full version or nothing I`m afraid.

ps: check for any of the enhanced commmands, memblocks, internet etc in the help, if they don`t show then it may be that you have already installed patch 1.13 at some point...now that I think about it, didn`t you install 1.13 to cure some graphics problem?, seem to recall something of the kind, if thats the case then even if you didn`t use the enhanced commands at the time, they will have expired by now.
