[Coco] Extract an .LZH file in OS9

[John Orwen]

Its been way too long since I ran a dos based BBS and extracted files 
and I am brand new to Nitros9 L2 now.
I downloaded a file from RTSI in a .lzh package to my PC and transfered 
to OS9 on my coco3 with Drivewire4.
I tried to extract the files in it by typing LHA x filename.lzh and got 
a message [ extracting filename ], two OS9 errors and a message [ 
damaged lzh file ].  Am I doing something wrong or missing something.
