DOM Error – An item with the same key has already been added.

I have been working on setting a new DOM module. I imported a test version of my model using the Excel sheet and Dom Designer automation script. After making some changes, I wanted to start over, so I deleted the module using the Dom Editor and tried to re-create it, but now I get the error:

System.ArgumentException: An item with the same key has already been added.

Any thoughts on how I can track down what key is already there? Or, better, how do I get rid of it?

Thanks!

Thanks guys! Completely forgot about the DOM tool in Client Test. That did help me figure out the problem was actually in my import file. I had a copy / paste error that resulted in two field names being the same. So, in the long run it was on my end all along, but the DOM Client Test tool helped me see that.
