Problem purchasing app on PC with Bluestacks

[cathm]

My music teacher uses iReal and it's fantastic, so I'm dying to buy my own copy of it to practice.
I only have Windows devices, and have followed the advice to install BlueStack.
However, when I go to the Google app store, it tells me I can't buy iReal as i don't have a compatible device!
Really hoping someone can help.

Here are some things to try:
1 close BlueStacks, restart device, open BlueStacks, try to purchase
2 in BlueStacks, log out of your account at Google store, log in again, purchase
3 try downloading another app from the Google store (to verify the store works)
4 contact support at BlueStacks for any suggestions
5 if you have other Windows devices, are you able to easily try on another? (tablet?)

It is the latest version of BlueStacks?
