Bought a game but it's not there?

I bought Minecraft Pe a long time ago and it is working fine, but I just got blue stacks for the PC and logged in and it says that I have to buy it again. My previous purchases show that it was bought but I can't install it because the price is simply there

At bluestacks you play the mobile version and not the pc version

Yes I know

If you buy Pc version you don't have a mobile version you have to buy it

I need the cell phone version because I play games with a friend who also plays on cell phones and I bought the cell phone version but it does not appear on blue stacks even though I have registered my Google account there
