A couple of questions...first, what version of Visual Studio are you running? Are you running the StrataFrame beta for VS2008? Finally, the BO mappper, regardless of version, has not changed much at all. When you start receiving errors like this, many times it is unable to reference the BO or search through the project. This can be caused because of a change made to a base BO (if in fact you have one).
Is that all of the stack trace that was shown. That is not enough information for me to troubleshoot. Also, when you refer to you changing your backend and rebuilding the BOs did you just rebuild your BOs from one type of database to another? Any additional help that you can provide would be appreciated. Thanks.

Exception of type "System.ComponentModel.Design.ExceptionCollection" was thrown.
I re-installed the Starta Frame with the same results.
Please Help.
