Can't initialize LimeWire: "One or more necessary files appear to be invalid..."
 

Running OSX 10.4.11
Have been using LimeWire version 4.16.6 for about a month with no problems.
Yesterday, attempted to open LimeWire and encountered this message:

One or more necessary files appear to be invalid.
This is generally caused by a corrupted installation.
Please try downloading and installing LimeWire again.
If the problem persists, please visit Lime Wire » Official Website & Free Download, BitTorrent «
and click the "Support" link.
Thank you.

Additionally, it gives me a crash report. I have pasted it at the end of this message. I have tried removing LimeWire and re-installing. I also tried installing the newer Beta version of LimeWire, but encountered the same issue [which is the version which generated the crash report below]. I am up to date on all Mac OS software updates. Any technical guidance on this matter is greatly appreciated!

Crash report:

LimeWire version 4.17.6
Java version 1.5.0_13 from Apple Computer, Inc.
Mac OS X v. 10.4.11 on ppc
Free/total memory: 17851608/19726336

If you can startup long enough to change the Theme, that may work.

Otherwise, to reset the themes back to default, go to your Home Library, and remove the themes folder in ~/Library/Preferences/LimeWire/themes/ while LW is shut down. Try again and see if that helps.
