Having trouble finding with the WebBusinessBindingsource control "The ApplicationBasePage could not be located"? I see from the forum that this may have to do with the assemblies being out of sync? My assemblies are at 1.6.0.0. I have the lastest version installed. I removed the assemblies and reinstalled SF with the lastest. The value for the items are "1.6.6.4".  Should this be correct?

VS2008

Yeah, the file version, not the assembly version, for the most recent beta is 1.6.6.4.  But that doesn't mean something else isn't hanging around in the GAC or even to the Program Files\Common Files\MicroFour\StrataFrame folder.  You might double check.
