I downloaded an XNA project from codeplex http://www.codeplex.com. The demo does not run. I get the following error message:

Microsoft Visual C# 2005 Express Edition
The project file FarseerDemo1 cannot be opened.
The project was saved with an incompatible version of XNA Game Studio Express or the project has become corrupted.

Anyone know what's going on here and how to fix?

We’re going to write a game using Microsoft’s XNA.  I joined a group (9 or 10 people) who want to do this. We had one meeting which was largely brainstorming.

After the meeting I downloaded Microsoft’s Visual C# Express Edition, its SP1, and the XNA Game Studio. I’m not even sure if I got all the official names of this sw correct, but anyway it loads and runs just fine and does not conflict with the Pro versions.

However, the SpaceWar example does not work on my IBM laptop. I get the following error message.

No SuitableGraphicsDevice

“Could not find a Direct3D device that has a Direct3D9-level driver and supports pixel shader 1.1 or greater.”

But it works OK on my Dell D800 Latitude laptop. Here’s a file that contains more detail about what I did along with some screenshots.
