Call of Duty: Modern Warfare starts running, then the BLZBNTBGS00000033 error message pops up. It seems that some of PC players have been encountering a BLZBNTBGS00000033 error when they try to run the Call of Duty: Modern Warfare 2019. If your copy of Call of Duty: Modern Warfare isn’t launching, I’ve got some tips to fix it.
The BLZBNTBGS00000033 error is caused by a payment issue or you need to activate the COD:MW where you bought it. That’s the solution. Go to the third party website (HumbleBundle, Green Man Gaming, Gamesplanet etc) that you bought the game code. Copy your code and redeem the code again to your Battle.net account. If the problem still persists, you can contact the website’s support team.
If you bought the game on the Blizzard Store and getting the BLZBNTBGS00000033 error, check your transaction history on your bank account. Probably the payment was declined.
