the errors your getting indicate the pc cant find the rom.i actually got the same error when i forgot to type inthe ".zip" file extension.
off the top of my head:
-you could have the name slightly off
-the file may be a different type(not a .zip)
-you could be in a different directory. if you have the sdk in your path,try cd:\
ing to the actual folder where youve put the file
-maybe a name issue? i dont think
your name should have any impact,but you might try shortening/simplifying the name.
-you also may try a different rom
ill ponder it some more the rest of the afternoon,im usually home around 8ish EST
