How do we properly configure local dev boxes using Visual Studio 2008 to deploy onto a server running Crystal Reports XI Release 2 .Net 2005 Server?

Question

In our scenario, a developer builds the web app locally and then we place it out on the application server. Recently, projects have been upgraded to Visual Studio 2008.

We have been having issues (such as the print control not functioning properly) and I want to see if they are related to the merge modules (or whatever else).

My first thought comes from looking at the Common Files\Merge Modules\ folder on a dev's box is that I see CrystalReports11_5_maps.msm, CrystalReports11_5_Net.msm, and CrystalReports11_5_NET_2005.msm.

1. Do we need the 2008 merge modules in there?
2. Do we need to remove the _NET.msm since we are using 2005 on the server?

It's also possible that the project wasn't built correctly with the merge modules but I want to verify what files should be there first in our scenario.

EDIT: The developer I'm working with currently is actually on Visual Studio 2005 and we still have issues.
