Re: PvZ2 on Bluestacks Not Working: SOLUTION
Hello Auntie hope you're well, not sure what went wrong with bluestacks but i think if you would have carried on with the installation process then Google play should have downloaded your gamedata from their backups.
Failing that there's always EA's email registration system backup and everyone's least favourite option that takes the longest, EA HELP CENTER.
But backing up bluestacks is good advice, you never know what's in the future.
