They are at the same address, just like I said.
Over 3000 confirmation and no stake.

Same address yes, but they need to be in the same unspent output as well afaik. So just send all of it in one transaction to a new address in your wallet so they will become one unspent output that will stake.
5050 coins staking.. another 24 hours and no stake..
I give up.
dont give up, just close the wallet and forget about it for a week. If you haven't already then sweep your wallet balance to another address so it will be in one large input - multiple small inputs will never get stake unless they are left to age for a very long time.
The easiest way for you to stake is once a week or fortnight, open the wallet in 1 or 2 weeks, leave it open for a day it WILL stake/until it stakes and confirms. then close the wallet and repeat again in another 2 weeks.
