Download and re-install the Crystal Reports components for Visual Studio - I would uninstall them first.
Crystal reports for Visual Studio downloads[

Remove the references from your Project & add them back in by browsing to the correct location.
I mainly work in C# but the same principle holds for VB, ensure you do not have the Crystal references set to Copy Local. If you do you will experience issues when you deploy because you need to install the Crystal Reports run-time on the machine you deploy your app to
