Hi
I have the same problem as scarred. When i finalize installing the plug in and activate it, the next screen is: you not autorized to access this page.
And /wp-admin/ becomes inaccesible, also when i login.
Delete the folder of the plugin is the “solution” to continue working.
I tried with the version 1.3 and wordpress 2.7.1 in blank installation with no other plugins.
Also in local.
Thanks.
