People having issues with windows 7 64 do this.

2: Plug in your USB Block Erupters
3. download http://zadig.akeo.ie/
4. go to options--> list all devices
5. select "CP2102 USB to UART Bridge Controler" and reinstall Driver. You just have to do this once.
6. create mediterraneancoin.conf file in C:\Users\<user>\AppData\Roaming\mediterraneancoin
in the config put:
rpcuser=user
rpcpassword=password
rpcport=9372
rpcallowip=*
7. Shift+Right click --> Open Command Window in the folder you installed the wallet and type in "mediterraneancoin-qt -server".
8. start mcproxy by running the bat file "runmcproxy.bat" that is with the wallet
9. start the cgminer http://www.mediterraneancoin.org/downloads/win32-cgminer-mediterraneancoin.zip
