When trying to claim the free Minecraft for Windows 10 copy, an error pops up saying "Error! It looks like we've temporarily run out of gift codes for Minecraft for Windows 10. Don't worry though, more codes should be on their way. Please check back later!". I have been trying for a few days with no results. Deadline to claim the code is April 20th, and I would like to claim the code as soon as possible.
