Really want to add the SIGNUP form to my site.. HELP PLEASE

I have tried two different plugins found on related to adding a sign up page which would allow people to signup on their own. Each time I get error messages. On the sign up page saying there is a problem with the Logo and randomly the install will cause the websites design to go out of wack. Can ANY ONE please provide a download that will work with the latestest version of Piwik? Thank you very much.
