After copying my project from 1 computer to another. I got this problem where visual studio is telling me I'm missing references. 

```
Import of type 'System.Data.DataSet' from assembly or module '<unknown>' failed
Import of type 'System.Drawing.Color' from assembly or module '<unknown>' failed

```

there a few more references missing but I'm assuming it's all part of the same problem. 

**Things I've tried:** 

* ensuring the project is building with .net 2.0
* ensuring the path exists to the reference.

Thanks in advance.
