I'm actually really bad at tech support. The upload page says:
To update your file, attach it here. Make sure the file you are attaching is a ZIP file, and the filename must start with a letter or digit; the rest of the filename can only contain letters (A-Z, a-z), numbers (0-9), underscores ("_"), dashes ("-"), and periods("."). File names must be at least 5 characters long.
So yeah, make sure you're trying to update with a .zip file, try replacing spaces in the filename with underscores and see if it helps.
As for the login issue, is it the Granary as well, the forums, or both?
