[Plugin: Piwik Analytics] Can't get it working with wordpress 3.0.1

The problem is, the installation file is located on my main domain on my shared hosting account. And I can’t change the Base URL path of piwik installation. I didn’t see any stats yet, while my website does get visitors/robots. So I’m assuming this plugin doesn’t work ‘yet’ for wordpress 3.0, correct me if I’m wrong and how I can fix it. Thanks in advance.
