Wasp error code appears when files fail to download correctly. Firstly, turn off your system and unplug the power chord for a good 10 minutes. Next turn off your modem/router for at least 60 seconds. After the wait time turn everything back on and try the download again. You should also try and secure a wired connection if possible. https://www.bungie.net/7_Error-Code-WASP/en/Help/Article/11897 Edit: Looks like UphillMercury beat me.
