I tried this on a spare computer and it seams to work with out any problems.  I then went back to my main computer and did the same thing. When I open the StrataFrame Business Object Mapper I get the following error.   Invalid object name 'DTEprojects.

I went back to the spare computer and backed up the StrataFrame database and restored it on the main computer with the same results.

I then reinstalled the 1.6.6 version from Sept 15, 2008 and again with the same results. I checked the Database Connection and it connects without any problems.

Please help

You must have an assembly update problem, possible due to some security issues in your computer.  Basically you have to make sure the old version of SF and its assemblies are removed from your computer, specially the ones from the GAC which you can do manually, then re-install the updated version and make sure you let the install update the SF database.

There several posting related to this kind of situation on the forum, I believe I saw one posted yesterday 10/23/2008.

I un-installed the StrataFrame and then reinstalled and all is good now.

Thanks again
