Are your laptops XP home or pro, or vista home or business? Have you watched Dr. Bertman's videos on the AC website?
I'll give a quick rundown.
In short, you need to copy all of the database files to the AC folder of the computer that will host AC. Then, you need to share the AC folder on the host computer. Next, reset the path to AC by going to Amazing Utilities and clicking reset path (or something similar). Now, open AC, it will have forgotten where to find the databases, and browse to the shared AC folder on the host computer. Select the Amazing Charts DB and you will be able to access AC on the host computer as well as on your laptop. You'll need to reset the path and browse to the shared folder on any other computers you add also.
I'm pretty sure I wasn't very clear in my post. If you have any questions I would be happy to help by writing out the specific steps. It'll be easier for me to help if your computers are XP. I haven't used vista much yet.
P.S. Mr Ref, where did you go?
