Could not load file or assembly

I got this error today when I tried to run an ASP.NET program from VS 2005:

Could not load file or assembly 'sorttbls.nlp' or one of its dependencies. The system cannot find the path specified.

Apparently "sorttbls.nlp" was a part of the .NET Framework. A few minutes before this happened, I had accidentally run the .NET 2.0 installer dontnetfx.exe by accident. I cancelled that halfway by choosing endtask. (which was not a wise thing to do.) So thinking this probably had to do with the error, I did a repair install of the .NET framework.

Everything's back to normal now.
