I'm running Windows XP myself

But others that are running OSX have downloaded it and I haven't seen any post from them that are bad.

I really not the right person to give you any solution when running OSX. I only use PC's

I'm sure someone has an idea to what the problem might be. Just be patient or try to fix it yourself while waiting for a reply. You might get lucky.

Only possible solution I have is that you might be running low on space on harddisk or java is outdated. But really I have no idea.

Might be an idea to post all relevant info. Setup etc. so others get an idea of the problem. Sorry I couldn't be of more help.
