You need winrar to download and use clients, if you don't already know this. You can download it
here.
Then download the silabsoft client
here.
Now just right click on the thing that says "silabclient" on the desktop and click extract. Click "ok" down at the bottom and a short processing bar will show up. When this is done, close the window if it isn't already shut and open up the new silabclient folder on your desktop. Now just double click on "run" and it should run!
Note: To keep the client running, you must keep the black box open. If you close it, the silab client will close.
Benefits:
-No more accounts being frozen! This client lets you fully load the areas.
-Rarely do you get the error saying "retrying in 5, 4, 3, 2, 1"
-Rarely does the client freeze
-Just like old RuneScape high detail!
Note that when you start it up it automatically brings up silabsoft.org forums in another window.
EDIT: The old link for downloading the silabsoft client was terminated, therefore I created a new one.
