Just did a test push of your SVN as a new file and it worked fine.
Selected a category, entered version, put in a description
Pressed [Generate Zip]
Looked at the zip it generated then pressed [Push Zip Live] notice this is not the first button and some people press cancel on accident.
There is a bug if you are creating a new project in our database with the SVN and you press [Cancel & Delete] during the 2nd step it will error the next time. This is only a problem when your SVN isnt tied to a project in our database and its the first time pushing live.
So when you make a new SVN not associated with a project in our database and you choose to push it live make sure you dont cancel. Otherwise you'll need to contact me to fix it.
