I am using a sandbox/developer account to do some testing. Using the ruby API, I am trying to void a transaction. I don't think I have changed anything on my end from what I can tell that would be causing this. It was working yesterday. Is it possible that there is an outage on the dev server?

This was the response I got from calling void_transaction()

{:success=>false, :failure_step=>:void_transaction, :error_code=>3, :message=>"Internal error", :error_key=>:internal_error, :original_error_code=>nil, :original_message=>"An error occurred during processing.  Please try again.", :user_error=>false}
