@altcryptomining All the sites you are mentioning are under a ddos attack since almost a week now.
To use the AIO Client I recommend to update to the newest version (https://sourceforge.net/projects/burstwindowswallet/) and wait until your local wallet is synced to 100%. The online wallet is not reachable from everywhere at the moment.
If the Local Wallet is not working for you, then go to "Help" -> "Clean up DB" inside the Client. If it still doesn't start up then something with your Java is wrong. Reinstall the 64 bit version would be a good start.
The Online Wallets are convenient but the whole point of this project is to have decentralization and independency by local wallets instances. Also the wallets have a blockexplorer build in.
