Using polar plot to plot distance/angle pairs

I am attempting to show updates of distance/angle pairs on a polar plot.
The data comes in as a single distance/angle pair, and the plot should
simply add the new point to the existing data.

To do this, I have created an instance of a polar plot. The following
details the inputs:

Data Array: a pair of distance/angle values that are put into a Cluster
and then an array.

Dimension: Numeric Controls with width set to 500 and height to 425.
The values are fed into a cluster and then to the polar plot.

Top Left Point: Numeric constants (0) fed into a cluster and then to the
polar plot.

Polar Attributes: A Cluster is fed to the polar plot. The cluster is
made up of the following:
A Numeric control, defaulting to 4000
A numeric constant set to 0
A boolean constant set to False
A boolean constant set to False
A color constant set to red
A color constant set to white
A cluster containing the Enum "Decimal" and a constant of 8
A constant set to 8.

When I attempt to save the VI, I receive an error message and the
following data in a file:

I would first suggest updating your version of LabVIEW to 6.0.2. Be sure to mass compile your personal VI's after updating LabVIEW. If this does not solve the problem try copying the entire block diagram of the problematic VI to a brand new VI. If this does not solve the problem you can send the VI to NI and an engineer will look at it.
