Hi! So as far as I can see you encountered 3 strange things
1) FindVUK cannot find the necessary data in the memory dump for the >GAME_OF_THRONES_S2_EPISODE_ONE▼< bluray.
>> in this case the memory dump should still be available in the dump subdirectory of the findvuk folder - it would be great if you could upload it somewhere and send me the location as pm so I can download it and check what is going wrong in this case.
You can check yourself with a hex editor if you can find the DiscId >AB6DAF1F77EEB06782525D440B84CF4F52D96452< in the memory dump.
2) FindVUK reported the found VUK to be invalid but it still works? Please post the logfile from such a disc - in case there's something wrong in my validation routine I'd like to correct it as soon as possible
3) The updater only updates 9 of 10 keys - well, please report this in the thread of the updater as honestly I have no idea why this is happening...
