Multi-site

Has this plugin been tested with multi-sites? I am attempting to use it with a multi-site and have encountered some problems.

Using a permalink URL such as
http://www.eyepromise.com/rewards/sample-site/daskal_tutorial/tutorial-1/
gets me a 404 error.

Using the post number such as
http://www.eyepromise.com/rewards/sample-site/?post_type=daskal_tutorial&p=69&preview=true
gets me the tutorial.

The “preview=true” part is necessary, otherwise I get redirected to the permalink and have the 404 problem.
