Can't open source code for VS2010 project

Hi

I have been looking at modifying an open source piece of software (here ... http://www.rainforestnet.com/crystal-reports-exporter/ask.htm)

I only need to make a small modification, so I downloaded the source code and tried to open the project in VS2010 but whenever I do it just shows up as "(unavailable)" and nothing I can do will let me open the project.

Would anyone be able to download the above source code and see if they can open the project - just to see if this is something I am doing wrong or there is an issue with the download?

All I need to do is change one line of code and recompile it but it's proving quite hard!

Thanks
