If you specified invalid login/password or wallet is not synced you will get different messages in miner. So probably you copied "primecoin.conf" file to wrong folder so wallet does not use it. Or you blocked miner in firewall.

- Wallet setup: copy default "primecoin.conf" file from miner archive to "c:\Users\YourWindowsLoginName\AppData\Roaming\Primecoin" folder, then start wallet.
- Miner setup: use default "miner solo sample.bat", just change xpm address, don't change login/password since default "primecoin.conf" file from miner uses them.
