Getwork support will be removed today, because JSON-RPC over HTTP for LTC mining is a waste of hashing power. Stratum/LTC support is available and well-tested for now.
Mining-proxy for Windows available for download here
. See FAQ, question #3 for info about proxy usage.
For LTC mining at our pool you need to start mining proxy with "-pa scrypt" parameter:
mining_proxy.exe -pa scrypt
After this you can point your miners to 127.0.0.1:8332, using your workers login/password for authentication.
