Could not load file or assembly System.Data.dll

[MikeWilliams-UK]

This error is caused by an missing file (which is part of the .Net Framework) on your computer.

It most likely happened durung the un-installation of another program, which has incorrecltly removed the file.

Microsoft have a tool which should be able to repair your installed version of the .Net Framework.
