1 GRC/day?!?

I run old AMD R9270x gpus and FX6300 cpu and get this:

My Gridcoin wallet is still broken:
Client Messages: "Stake Weight 10049532; Searching for coins Out of Sync"
I have no idea, how to fix this: deleted grc files from AppData folder, downloaded blockchain again... nothing!
So, I think, I'm done with Gridcoin... sell my little bit (11 k) and run BOINC just for fun :)
