Maybe nobody's helped you because they don't know what the problem is...your post's really confusing.

You say "now disregard update. It is back to loading messages. Please see update after question 16". Well the update after question 16 says that you have a connection problem...is that the problem, or are we supposed to disregard that bit??? Is the connection problem solved now, but there's still a 'loading messages' or 'loading internationalization support' error???
Do you see how it could be confusing the hell out of people?

If your LW won't connect, try the fixes here: If LW Will Not Connect

If you're connected, but still get no search results - try the fixes below:

1. In LW go tools > options > searching > basic & check whether the 'show license warning' box is ticked. If it's ticked , untick it > Apply > ok...see if that makes any difference.

2. Problems with the search

3. Delete LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).
Fixes for LimeWire
This will change all of your settings within LW's options, you'll have to go back through afterwards & reset things to the way you like them.

And if you're still stuck loading messages/internationalization support, check here: Connection problem with PRO - "Loading Internationalization Support" never finishes!

If none of those are the problem...slow down & try to describe your problem in terms that we can understand
