Java 1.5?

Hi all, ive just bought LW 1.41.8 pro as my previous version seemed to be dying! anyway installed ok but as soon as i try to open it i get this:

Could not launch.... This application requires Java 1.5 or later, but only the following Java versions are installed: 1.4.2, 1.3, 1.3.1, 1.4. Updating to a newer version of Mac OS X may resolve this.

As far as i can tell there isnt a java 1.5 for 10.4 and mines all up to date (1.42)!

has anyone got an idea what i should do?
thanks.

1. Setting up Java 1.5

2. SAFE Boot & Repair Permissions which should be done after any installations or updates.

3. Delete your LW prefs folder whilst LW is closed found here: /Users/your_username/Library/Preferences/LimeWire

4. Don't share more than about 1,500 files. If they are mostly video files then reduce it a little more.

5 Tip: Purge the Downloads Queue! (click on blue link)

i suggest u
Upgrade to OsX 10.4.10 too...
