how do I fix google play on my android cell phone

I have google play on my phone but it will not allow me to access it says I have to redeem something in order to access and have to upgrade my gmail account not sure what is going on and I am unable to unload it and reload it on my phone because if I unload it I will not be able to add it back on at least I think that is what would happen
