 * Upgraded, and that error is gone, only to be replaced with 16 others. :/

 * It’s best to delete your old files first before uploading the new ones.

 * If you can get into your control panel set your time offset to zero. Then try
   it again. I got something similar to this and it makes sense in that a timeoffset
   different than your server’s could potentially trick the call into thinking it
   has already been sent at some point in the past. (Well, that’s at least an uneducated
   guess without a lot of thought put into it.)
