ODM Tools: Statistical Summary Error

WaterAnalyst[CodePlex]
When I try to visualize a range of data that includes the date August, 20 2009 (I don’t think it’s that date in particular, I think there is something about the Values data from that date that is causing the issue) I get the following error message:

“An Error occurred while calculating the Statistical Summary for the Visualize Tab. Message = Index was outside the bounds of the array. Index was outside the bounds of the array”

The graph then displays correctly but there are no summary statistics. The data appears to be sound, the only potential problem that I can see is that we received a large storm that day and the maximum Precipitation for that day is the largest in the dataset.
