wait... does your config file literally contain these lines at the beginning?:
Your error message seems to say that these lines are in your file?
If so, I'd suggest removing the first two lines ("It have format:" and "Code:") as I think you've copy/pasted something from some instructions incorrectly. Your config file should only contain the following (NOTE: DO NOT copy the "code:"... only copy the text INSIDE the box starting with "rpcuser":
rpcuser=here you enter any word with several alphanumeric characters
rpcpassword=here you enter any word with several alphanumeric characters
listen=1
port=11994
masternode=1
masternodeprivkey= along with my key and now I cannot open wallet.
You should be able to modify the file with any text editor
