You have to use the information for samsung. Either wait until after midnight, or change the dates. See Block bar thread.
Note, the first time you get maria v15, and can click it many times, load up as much as you will ever need in case it is gone after a few days or if you want to upgrade to v1.3.1.
I dont know if the same thing will happen with v1.3.1. Just try it. Worse case clear data and start again.
