Find your order

Open your purchase confirmation and copy the license key. You will redeem it on the portal before downloading the loader.

• Check your inbox for the purchase confirmation — also check Spam / Junk.
• Look for mail from SellAuth or noreply@sellauth.com.
• Open the email and use View Invoice to open the checkout / order page.
• If checkout is already open in your browser, skip the email step.
• Go to the Order tab, copy your license key, then continue with the steps below.
• If you cannot find your key, log into the customer dashboard with the same email you used at checkout.

Phase 1 — Account & loader

Create a portal account, redeem the key, and generate your loader.

• Visit the client portal and sign up for an account.
• Sign in, open Account, and enter your license key to activate the product.
• After redeeming, generate your loader from the dashboard and download it.

Phase 1 — Disable antivirus

Windows Defender will block the loader if real-time protection stays on.

• Windows Security → Virus & Threat Protection → Manage Settings → turn off Real-time protection.
• Optional: download Defender Control (dControl), unzip, and run it to keep Defender off.
• If the browser blocks the download, open the downloads bar (⋯) and choose Keep anyway / Keep.

Phase 2 — Launch the loader

Run the loader as Administrator. Right-click the executable, choose Run as administrator, then log in with your portal account credentials.

Phase 2 — Select Fallen Survival

Once logged in, select Fallen Survival from the product list in the loader dashboard.

Phase 2 — Wait for ready

Wait until the loader shows a ready or waiting status before opening the game. Do not launch Roblox until the loader is ready.

Phase 2 — Open the game

Launch Roblox normally and join Fallen Survival. Wait until you are fully loaded in before doing anything else.

• Once in game, give it a few seconds to initialize — do not click or move immediately after loading.
• The client activates automatically when ready. Play responsibly.

Troubleshooting

If something fails, check these first before opening a ticket.

• Loader won't open or closes instantly — re-disable Defender, re-download the loader, run as Administrator.
• Invalid game version or invisible UI — fully close Roblox, wait for the loader ready state, then rejoin.
• Failed to connect / network error — check VPN or firewall rules, then retry login.
• Auth error or failed to sign in — confirm the license key is redeemed and you are using the correct portal email.
