I had already started playing D3 with patch 1.04 for one day for my Wizard's character. Now I am at Paragon Level 4. For those palyers who had problems updating patch 1.04, you can try this method:
How to patch Diablo III?
This may apply to you if this is how your game/launcher is behaving:
On login you get a message saying "A New patch for Diablo III is available" and it also says that your game will be closed and the patch will be applied. The game closes, the Launcher comes up saying "Game is up to date" and no patch is applied.
Basically, the "new patch" message means your Diablo III.exe or battle.net.dll does not match the version accepted by the server. If different regions are at different versions, you need to set your patch_url to get updates meant for the region you play in.
(July 11) EDIT: Now that all regions are at the same version, you shouldn't have to do this anymore. If you're still getting the "new patch" message, it means your battle.net.dll is probably missing or corrupt and changing the patch_url wont help.
---------- Change the patch_url by editing the .agent.db file.
This is how you can set your client to get updates whenever they're released in the Americas region: (Shouldn't be needed if you use a client meant for the region you play in.)
Before you start, make a backup copy of the original .agent.db file. (to restore in case something goes wrong)
1. Go in your Diablo III folder.
2. Open the .agent.db file on WordPad.(This file may be hidden and please, do not delete this file)
3. find the "patch_url" line and change its value to:
4. Save and close the file.
1) Find ProgramData (hidden folder)
2) Find Battle.net folder
3) select and delete the Agent folder
4) Start the Launcher
