ltcminerYes, you can. But first you need to unlock your wallet. You can't run p2pool or solo mining while your wallet is locked.
Run this command using RPC console:
walletpassphrase "password" 86400 true
This command will unlock mining for 24h, for example.
P.S. Are you sure you want solo mine at diff 96?

I agree with Balthazar, 96 (scrypt) difficulty is much to high to solo with a couple of GPU.
If one was running a few rigs (Like myself), you would want to run a private Pushpool if soloing.
I run between 3-4 M/H for scrypt based coins, and my cutoff (My opinion of course..

) is low to mid teens for difficulty.
Find a good PPS pool, for whichever coin you want to mine.You will get the benefit of a definite payback, instead of risking getting nothing except a high electric bill when the difficulty is at the current level.
