oh .. LimeWire program will not open?

1. Which OSX version are you using? (example: OSX 10.5 (Leopard), 10.6 (Snow Leopard), 10.3 (Panther), 10.4 (Tiger), etc.

2. Which model of mac computer do you have? (a) MacPro, iMac, MacBook Pro, MacBook, G5, G4, etc.? (b) model? (c) details of computer which can be found under apple menu top left of screen 'About This Mac ...' such as processor speed, memory ram.

I'm wondering if you have a non-intel model of mac & the newer version of LW will not run on it. Else it's most likely an OSX Java installation issue.
