urgent help please

I had just installed seo4smf mod on my smf 1.1.7 forum. But after installing it is giving the wrong http address through which all page is showing error.

For example, after installing seo4smf url is

http://indiadailyforum.com/packages.html;sa=installed ( not working)

before installing seo4 , url is

http://indiadailyforum.com/index.php?action=packages;sa=options ( working)


 What should I do to uninstall this seo4smf mod as I cannot log in to admin options because the logging in http is showing error, any help please
