Judy I don't know if you cover this in your tutorial as I didn't look but what happened to me was I didn't know you had to pay attention to the size of the pic of your fabric and when I copied my fabrics into my EQ5 I ended up months later getting a no more memory message. When I called the company she told me I needed to reduce the size of my pics.
I did some but now I just pay attention when I add new ones and make sure they are not huge.
Another thing I wondered if anyone else has had happen- I sometimes get a message on some of my eq files that it won't let me open it. It will give me an error message.
