Repository Browser Malformed XML

Hi,

I am using SmartSVN 7.5.3 on MacOSX.
When I open the repository browser and try to browse a repository I get the following error: Malformed XML
This happens when I have the URL in the following format:
https://myserver.com/svn

I accidentally entered this url and after that it doesn't work even if I enter the correct URL which worked before:
https://myserver.com/svn/repository

The SVN server URL is 100% correct. It worked before and my colleagues are using the server and the projects that I already configured are also working.
New checkout, new repository browser stopped working after I entered the URL without the repository.
I think it tries to use the old URL(which gives Malformed XML error) even if I enter the good URL.
What could be the problem here? Or how could I clear the remembered URLs in the repository browser?

Thanks
