Did you miss --scrypt by any chance? Looks like it.
yes i didnt use it, because when add it, just start and disapear.
Get cgminer 3.7.2. Use --scrypt option. Run from windows command line ("cmd") so you can capture any errors.
That's not going to work for him... he's trying to use a USB ASICminer Block Erupter on Middlecoin.
so i cant use it in this pool ?
yes i use USB ASICminer Block Erupter
Like I said in my other post above...
You should be using that USB miner to mine on BTCGuild or a Bitcoin P2Pool node.
It won't work with ANY Scrypt based pool. Only SHA256 based pools for mining Bitcoin (and other compatible coins) directly.
