[Q] perfect keyboard topic

hi, very sorry if this is in the wrong place,

i have been using perfect keyboard free for some time, today i wanted to remove some words from my dictionary so i paid for the pro version,

the problem i now have is the keyboard layout has changed, i use the old number style pad not the querty one (fat fingers)

i have been looking but cant find a way to download an older version to my phone, any help would be much appreciated, thank you.
