Symptoms: When you open a project created with a previous build of ActiveReports after installing a new build, there are errors related to being unable to find the previous build.
Cause: Visual Studio 2005 has a new property on references called Specific Version. If this property is set to True, the project lookos for the specific version and throws errors when it cannot find it.
Solution: Delete the ActiveReports references and re-add them. (In Web projects, do this from the Website menu, Start Options, References tab. In WinForms projects, do this from the Project menu, ProjectName Properties, References tab.)
