Sounds like you need a specific version of LW, PLUS the matching Java suite. Take that up with Lord of the Rings and i believe you can ace the problem. In this case does the Ap ever launch at all? (Menus at top,) or does it just report: wrong Java?

I'm glad you got two macs. I hope you got PhotoShop or some other graphic aps that allow you to fully enjoy them. I'm running this 400Mhz Blue G4 tower because it's fun, but it's nothing compared to mom's iMac in the other room. (Her's has 10.5, but what a drag, no Classic, and here I am still using Freehand 7. PShop 5.5, and Word 4.0, as shareware, circa 1991!)

Back on point, only one LW version runs on this OS-X10.3.9:
[ LWire 4.12.15 with Java 1.4.2 ]

You gotta dig through their older downloads to get it. Perhaps a refund is in order in your case if they don't have a similar older Pro version. Although it's very slow, this free version has more than met my needs.
