1. I have executed the update.bat file to update the client automatically, but it's still saying that client is outdated, what should i do?

• Remove all unzipped folders from your main client folder, for the client works you just need to leave data.zip, exe and dll files.

2. Sometimes i'm expecting some lags issues (stuttering) in client.

• Some video cards have issues with GL client, try to use DX client instaed. If lags persist, go to option -> graphics -> enable walk fps synchronization.
