Thank you for taking the time to create a CodePlex account to report this issue.

Any additional information you can provide, especially if you changed any of the default options (such as unchecking 'table' processing...) would be appreciated.

Not a problem, happy to help.

I believe the issue may relate to permissions, as a collegate was able to successfully use it with the default options without a problem, but I receieved this error. I even reduced the options so that it wasn't checking indexes but the same issue came up. I had the administrator connect me directly using the sa password and it worked.

From what I can tell looking at the source, it is attempting to set the owner of the index class from the owner property of the "parent" object, which has returned null. I found the query that was used to populate the data for this loop and I could successfully run the query directly through SQL Management Studio without problems, so the issue may be relating to some obscure permissions that simply having db_reader was not sufficient for. I would recommend that some exception handling could be added that allowed you to skip individual issues, allowing the rest of the comparison to go ahead rather than stopping the entire comparison based on one minor issue.
