Mega evolution is not yet coded, so you won't find Key Stone and Mega Stones either. But I think they said in very distant future they will try to implement it, so please be patient and wait.
Have you extracted the game?
Try to run the game in admin mode, and compatibility mode; also add an exception to your firewall and antivirus if you haven't yet;
Otherwise: Have you tried these following steps, already, from the Read this before making a General Support topic ?
Something for this idea:
1-4th Gen grass starters rarity tier should be 9 while 5-7th Gen grass starters rarity tier should be 9+ (special) till they representing regions added.
For possible accesess points the best would cities with Grass gyms: Celadon City (Kanto), Eterna City (Sinnoh), Coumarine City (Kalos).
Officer Jenny bounty for catching Pikachu in Pewter City has big type. When you don't have Pikachu in party you show not Pikachu to her text for showing wrong Pokémon to hear says sentret instead of Pikachu. Server Red.
A moves animations is not high priority, so it won't happen any time soon espacially when there still a lot stuff to implement and a lot stuff needs to be updated to current Generation standards (Gen 7 V2). So be very patient about moves animations. :)
And plus there is new Pokémon MMORPG being made by some of PRO staff which is 3D and people call this game as PRO 2. Plus this game has Party system like I wanted, like Pokémon Cyrus had.
My hopes and wishes for Christmas Event:
Alolan Ninetales added as a Mount and maybe as well Shiny Alolan Ninetales Mount.
Alolan Sandshrew and Alolan Vulpix added to game and is catchable at Christmas event.
Wailmer Surf Mount or other Surf Mount like previuos time.
