Let's cut right to the chase, the AIR client (more recently called the legacy or old client) will officially be disabled and turned off on April 24th. For more information on what the updated client offers and why we’re making this change, [check out this article](http://na.leagueoflegends.com/en/news/game-updates/features/legacy-client-officially-retires-april-24). This means that if you try to launch the old client on the 24th, you will immediately be prompted to switch over to the new Updated Client. You’ll get a notification that looks like this:
We’ve been preparing for this on the backend for a long time, so there shouldn’t be too much you need to download when the switchover happens. Once everything is set, you should be able to login normally. We ***_strongly encourage_*** you to switch over starting now! That way if you do hit a problem we can get it resolved while the AIR client is still there as a back-up!
We know that with any change there is always a risk of some unforeseen bugs and errors that may crop up. The following issues are some of the most common that pop-up with their solutions:
*NOTE: You may want to [temporarily disabling your Firewall](https://support.riotgames.com/hc/en-us/articles/201752664-Troubleshooting-Connection-Issues#wq3) before switching over to the Updated Client, and re-enabling it the moment its finished. This should help the switchover go smoothly.*

>#***Why does the End of Game Stats screen take FOREVER to freakin' load?!***
This might be due to the "Close Client During Game" option in the client. This option makes the client close out when you enter a game, which means after the game it has to completely reboot to start. Low Spec Mode should be enough to keep things running smoothly, so disable this option by entering the client, clicking the gear in the upper right hand corner, a[nd unchecking the box.](http://i.imgur.com/smwR8be.png)
>#***“I’ve tried the Updated Client before, and it was sooooo laggy”***
We've made some massive changes to the Updated Client make it run as smoothly as possible, even on the proudest of potatoes. Enable Low Spec Mode if it isn’t on already. You can find out by clicking the gear in the upper right hand corner of the Updated Client and then [click "Enable Low Spec Mode"](http://i.imgur.com/rPGRnYW.png)
>#***"Patching Failed and we're not sure why Error: 004"***
This error usually occurs when Operating System Permissions isn't set properly. Essentially, the patcher is trying to access files found on your hard drive, but it is being denied from doing so.

>#***"Something's up with our servers and it's preventing you from patching" Error: 003***
Occurs when the patcher isn't able to maintain a stable connection with our Patcher Servers. If the patcher loses connection to the server to get the necessary files, it will simply stop working.
