Just in case you missed the other post, or if it hasn't happened to you yet, here's the quick deal.
LimeWire brings up a window telling you of an internal error, and asks that you copy the text in the tiny box and email it to their bug department. Minutes later, you get an automated response, like this:

-------------------------

This is an automated bugs@limewire.com email response.

Your submission to bugs@limewire.com indicated that you are using a buggy version of LimeWire that requires change. Please visit the LimeWire download page and switch to the current version. This may involve a rollback to version 2.7.13.

The problem with their advice is in that the link points to the free version of 2.8.4, and the pro version still points to 2.8.5.

The subject of the message states:

Please change to the current listed version of LimeWire.

Boy, that must have been some eggnog they were smoking at the Xmas party.
