加载解决方案时，Visual Studio 2008崩溃时出现故障

I've downloaded the source for SubSonic via SVN. When I try to open the project in Visual Studio 2008, it converts the solution, loads all the projects then disappears without an error message. Subsequent loads of the solution do the same. If I run devenv /safemode and then open the project it works fine, but I can't use any add-ins.I've downloaded the source for SubSonic via SVN
