I think that you have two instances of the Crystal Reports library in your project references. Go into the references and delete all references to everything related to Crystal Reports. Then go into Web.Config and delete all references to Crystal Reports again. You have to do this in both places.

Then go onto any one of your forms and add  a new dummy report to it. This will trigger VS2005 to create new references to the latest Crystal Reports libraries. Once that is finished you can delete the dummy report. Now you should just have references to the new Crystal libraries.
