Hi there! I understand you're having trouble logging into Creatures of the Deep, and it seems related to "Data valid gk bisa login" — which I take to mean some issue about data validity preventing login. Could you please tell me a bit more? For example, are you getting an error message regarding invalid or corrupted game data when you try to log in? Also, did this problem start recently, maybe after an update?

In the meantime, here’s a good starting point to help resolve login issues related to data validity:

1. Restart Your Device: Sometimes a simple restart can clear temporary glitches.
2. Check Your Internet Connection: Make sure your connection is stable by trying another app or website.
3. Clear Cache of the Game: On your Android device, go to Settings > Apps > Creatures of the Deep > Storage > Clear Cache. (Don’t clear data yet, as that may lose progress.)
4. Reinstall the Game: If the error says invalid or corrupted data, uninstall the game completely and then reinstall it from Google Play. Before uninstalling, ensure your game progress is backed up via Google Play Games or your account.
5. Login to the Correct Account: Particularly if you use Google Play Games login, check that you are signed in to the right Google account that holds your game data.
6. Restore Progress if Needed: If you lost progress after reinstall, you can try restoring it by logging into your saved account inside the game.

Could you confirm if you have already tried any of these? Also, do you know if your game data is linked to Google Play Games or another service? That info will help me guide you better, or if necessary, we can try some advanced troubleshooting based on your exact situation.

Looking forward to your response!
