Hi,

if you load the package you got the message but ZeroMatrix[]
is still working and asking for BlockMatrix[] gives

BlockMatrix[block] is an obsolete function. Use ArrayFlatten[block] \
instead.

and this will probalbly answer your question
"... what *should* I be using now instead of "BlockMatrix", 
"ZeroMatrix", etc.? "

and forgot the Help Browser -- the good old Information[] is
mutch better ...

Regards
   Jens
