Jeepers, Mike never sleeps! 
Lucky me, just got home from work. Before midnight for once! No big roller derby party this weekend, it's NASA documentaries and amiga.org for me, this exciting Friday night, instead.
Now on to the guy's problem, I'd ask the usual questions. Did lha work previously (and just now stopped working), or is this the first time using it? What sequence of commands is he putting into it? Does it work if he copies it to ram:, etc. There's so many ways to troubleshoot this, but without more information it's kind of hard.
