Heh yeah was about to come in and say i figured it out. You are right, i thought about what new additions you made to the latest version, then realised you added Neoscrypt and Lyra etc. I had already manually created them, however i called it Neoscrypt, you called it Neo Scrypt. It took exception to that. Wouldnt let me delete one within MultiMiner, had to edit the xml manually. Removed my one and it did the trick, All operating.
(Not sure why id would stop me starting the miner, as I was using x11 and not Neoscrypt...)
