Can not see the LSB of Rey and starkiller on web store,

Unfortunately, it doesn't work. I tried a lot to fix the problem of payment and region and I can pay all other LSB or pack from the PC gaming. While I can't buy the two 'old' LSB that I didn't buy (Rey and starkiller). On webstore they just don't appear. On PC they are there but an error pumps out Ref 54001 while all other things are available.
