butterworth fpga does not compile

[stoughto]

I'd like to use the Butterworth vi in FPGA. I can drop the node, but when I try to configure it via Properties, any change (for example, in cutoff frequency) gives an error, such as: Butterworth Filter: Unexpected XNode error occurred Details: This node has experienced an unexpected error. Please redrop the node or contact National Instruments. Attached is a zip file with a trivial example: a constant wired to the input of the butterworth vi, no loop. I have Labview 2009 SP1 on Windows XP.

Your zip file is missing from the message.

Here it is now.

Let's try this.

I just ran into this error and I was able to fix it by clearing my object cache
