The launcher refusing to download the update may be a connection issue. Power cycling your home network may help with the download.
Power cycle your home network:
- Turn off the router by unplugging it. If you have a modem and router in one device, turn it off then proceed to step 3.
- Turn off the DSL or cable modem.
- Note: Some modems are equipped with a backup battery. If your modem has one, please remove the backup battery to completely turn off your modem.
- Turn off all computers attached to your network.
- Turn on the DSL or cable modem first and let it boot. Let it complete its connection to your ISP before proceeding to the next step. If you have a modem and router in one device, proceed to step 6 after it connects to your ISP.
- Once the modem completes the connection to your ISP, plug your router back in. Let it complete its power on test before proceeding to the next step.
- Restart your computer(s).
