Piwik doesn't track anymore

Hi,

2 days ago I installed a couple of plugins and since then, Piwik isn’t tracking any hits any more.

One of the Plugins was the “better geo localization” plugin and I think this is the culprit, because it altered the database.
Since my first version (0.5.something) the database was altered a lot of times but without any problems.
Is it possible to reinstall piwik on a different domain with a fresh, clean database and reimport the data from my actual, altered database?

A dump of the old data with following import into the clean database won’t help because the structures don’t match anymore.
Is there a tool for such a task? Exporting only data that matches the structure of the original database after a fresh install?
And what do I do with the archive tables? Can they be copied and they will be correctly recognized?

I don’t know if it helps, but this is my actual structure:
