I do not use the integrated wallet miner. I use primeminer_v08_rc1
I also do not solo mine. I use
http://beeeeer.org/
If you need additional help, here is my bat file:
primeminer_x64.exe -poolip=54.200.248.75 -poolport=1337 -pooluser=YOUR WALLET CLIENT ADDRESS -poolpassword=PASSWORD -genproclimit=4 -poolfee=1
pause
The only thing you need to edit is enter the poolip which I have above, poolport is the same, and make sure you enter in your wallet address under pooluser. Pool password stays PASSWORD. Lastly, genproclimit tells it how many cores to use so for a quad core I use 4, for a quad with HT I usuaully use 7 because 8 actually gives me the same or slightly lower primes/s.
