I recently downloaded Lucky Patcher 9.5.0 and installed it to get some IAP for Yu-Gi-Oh Duel Links. 

After going through the tutorials I went ahead and went to the shop to purchase some packs. 

Unfortunately it did not work, I even restored the order of purchase or whatever and it still did not work. 

After each failed attempt, it showed "Error 2100 Purchase Failed".

I am not sure how to fix this, should I wait for a custom patch to come out?
