Hi,
I have 2 PC's using the same wallet file but suspect something is wrong.
Looks like your first wallet is on a wrong chain. All those stakes will be invalid on the good chain.
You need to delete everything in your appdata/dopecoin directory EXCEPT for wallet.dat
Then start the wallet with -rescan option and let it sync from scratch. This should bring you back to the right chain.
If syncing from scratch takes too much time, you can use this blockchain snapshot:

That's what probably caused the fork.
