I am working with a non profit environmental institution in Panama that wants to upload pictures of natural landscapes to Wikimedia Commons.   I found the GWToolset and have been reading how to use it and preparing the metadata to run a small test.  

Recently, with the help of  Fae (thanks a lot!) I was able to produce XML files for our metadata and I was set an account in the test servers of GWT in:

I finally could try the tool and got this error message.  I would appreciate if anyone could explain me how to fix this.

There was a problem processing the metadata file.

There is no <templatedata> block for template Information.

If possible, add a <templatedata> block to the template, or to the template's TemplateBox.

Thanks
