I sent Phore to my Win 64 wallet. I set up a password and unlocked it for staking. It says Staking active Multisend is not active. Wallet is open for 3 days already and i got no reward

i am doing something wrong but i don't know. Can someone give me an idea?
btw: when i try to tools -> open wallet configure file; windows says payment request file cannot read
I believe a balance of 1000 PHR would give you roughly 1 stake every three days. But even then, it is on average, meaning you could easily go a week without any stakes, but you could also get 2 stakes in a single day. Over a long time it would average out to one stake every three days.
