Yeah -- definitely try again. It should absolutely work on Win2k (that's what I use at home).

if it fails, go into jEmplode2.lax in your install directory, and look for a line that says:
lax.stdout.redirect=something
set it to
lax.stdout.redirect=C:\\debug.txt
(notice double backslash)
then add a new line
debuglevel=56
then run the app, drag and drop, quit, and send me the output of debug.txt
