Yes. Early access ends today. That is why a lot of people lost access today. They are not aware of the three codes. As I mentioned in an above quote, there are 3 codes. Pre-order code, early access code and the actual Stormblood code. The actual Stormblood code was only released on 20th June.
I am going to reiterate my points.
If you bought a physical copy and the mail has arrived, you should have a new code inside to register on the Mogstation.
If you bought a digital copy from the SE store, check your orders on the SE store again. Press the "unlock code" link. You will have a new code to register on the Mogstation. This new code only appeared after 20th June. If you did not key in a new code anytime after 20th June, that means you only keyed in the early access code. Early access has ended, that is why you appear to have lost access to Stormblood.
Where to get your actual Stormblood code (after 20th June).
1. To obtain your code, visit the Square Enix Online Store and log into your store account.
2. Select the "Your Orders" tab, and find your Stormblood digital purchase (Standard or CE).
3. Click "Unlock Code" and you'll be taken to a page displaying your code!
4. Follow the instructions on how to redeem the code on the Lodestone!
Where to key in the new code.
http://eu.finalfantasyxiv.com/lodest...4810126cae069f1. Log in to the Mog Station using the Square Enix Account on which you wish to play Stormblood.
2. Select the service account to which you wish to register Stormblood.
If you have multiple service accounts, click each tab under "Select Service Account" and check the character list to ensure you select the correct account.
Once you have chosen the desired service account, click "Manage Service Options."
3. You will now be taken to the "Account Services" screen.
Double-check the character list and World names to confirm you have the correct service account, then click "Enter the Registration Code for the Expansion."
4. Enter your 20-digit registration code in the field at the bottom of the screen, then click "Next."
5. Confirm details. Registration cannot be canceled after this step, so be sure you have selected the correct service account before clicking "Next" to complete the registration process.
6. The registration process is now complete.
Click "Return to Your Account" to confirm your account details.
