Error: Object reference not set to an instance of an object

When I attempt to perform a data compare between two databases, I receive a message that the compare is aborting. This happens during the "Registering databases" phase and the action underneath it says it is "Reading object text"

At the bottom is the message saying "Object reference not set to an instance of an object"

Any ideas. I compare these two databases frequently using SQL Compare 5.

Thanks.

    We think we have a fix for this issue, but the problem we have is that this error message can occur for a number of reasons. The first step to debuging the problem is for you to run a SQL Server profiler trace as the databases are registering. Stop profiler after the error has occur and send me the trace. I will then advise you as to the next steps, if you have some example schema of the problem that would be useful too.

    Jonathan,

    Thanks for letting me know you found a fix which will be released in a couple of days.

    Can you tell me how to get the release, once it's available? Will it be posted to these boards or can I run the "check for updates" within the application to pick up the fix when it comes out?

    Thanks
