If your hosting plan includes statistics monitoring, we have upgraded our monitoring software to revision 4. with this improvement come minor preference changes that you will be prompted to change at your first log in.
At the initial screen, you will be prompted to update your default date range, default rows, and chart type (advanced or standard). The preferences default to this advanced SilverLight option. To not use SilverLight, you will simply need to change the pull down menu to standard.
If you do choose to use the advanced features, you will have the opportunity to download and install Microsoft's SilverLight.
