So I already did things like
1. I deleted the old game, and redownload everything from scratch (again), this time I choose the 3rd option (download per parts, because its faster), did the thing, run the game, but still got that problem.
2. I tried to add game launcher and folder on Windows Defender Whitelist. Still got that problem.
3. Delete the L10N folder, check the files, redownload, and play the game, still got that problem.
So, any other solution?
FYI, Im also install AION classic last week, and its run fine with no problem. So Im guessing its not because Im using windows 10. I wonder what went wrong here. Please help.
