Have you recently updated to .Netframework 4.0? If so, what version was it before 4.0? I personally find it best to upgrade from one version to the next, till you are current with present version....it is known to have issues if you go from say Version 1 right to version 4. Also you might wanna try reinstalling Amazing Charts. The exception point is saying that you are having specific issues with AC.
