Same here. Comp didn't remember it,so I used the link in the e-mail as Andy's reply said to do. Works great now. I think the problem comes in when you use microsoft's "free up disk space" program to clean out thubnails,forms data,etc. It cleans out the area of memory where his data would be stored. Just use the link in the e-mail that you reply with to initialize Labelizer.
I've gotta say this program makes the nicest labels. I have been getting rave reviews for my labels. I love the ones where I can add my own photos. I like the squarer one the best because it fit the avery label easy peel stickers so nicely. What a great find!
