I just downloaded the new 2.7 version and I keep getting a fatal error when I try to run the program. Can anyone help?

I just downloaded it and it blows up with a java error. Here is the important feedback from the error:

LimeWire version 2.7.3 Pro or above
Java version 1.4.0_02 from Sun Microsystems Inc.
Windows XP v. 5.1 on x86

Similar to above, I have loaded and reloaded new version several times with no progress. Had zero problems on any previous versions.

there seems to be a problem loading the collections.jar file. Try re-downloading & re-installing.
