I receieved the following Error number when doing an upload for a change set.  I am attempting to upload email templates built in Production, and bring to Sandbox.  I receive an error message that says to contact Customer Support, but when I open a case, I get another error message, "Developer support for standard customers and partners is supported directly through our community.  If you have a developer support question, please click here."  

Yet, when I attempt to click on any of the case fields, its blocked out, and I am unable to submit the form.  Does anyone know what the Error Number is?  A google search did not help.  

Error Number: 1013122098-267274 (-476769046)
Please try to upload your change set again. If it does not succeed, contact Customer Support and provide the error number listed above.
