Gapps crash

Hey guys,

I've a brand new Note Pro.

I've flashed this rom: xiaomi.eu_multi_leo_V6.6.5.0.LXHCNCF_v6-5.0

The problem is it comes with the play store. When i open it i get the error: Google play services has stopped.
When i try to flash Gapps it also gives an error, saying it has a different version already installed.

Anyone that can help?

Thank you
