No, that's not it at all. How can we run them at the same time on the same computer? When he runs it on his account it works, when I run it on my account it doesn't work.

Also, awhile ago it was working fine. And now suddenly it isn't. I've had this problem before where it spontaneously stopped working. I didn't do anything and it started working again. Now it's stopped working yet again. Is it so hard to turn out an effective product?
