There is no fix for this as of now, the only way to play for us having this problem is to switch to DX9. Although you can switch and be able to finally get in the Queue is gonna be in the way, weather your Queue is around 2k or 8k it doesn't matter you'll get and Error anyway and kick you out of the game without queue protection, i've been on queue for like 3 hrs started at 9k and got and error around 5k saying "Yo you paid for the DLC but nope we didn't planned ahead of this and we didn't add server capacity before release we also delayed it so that we have time to prepare for the waves of complaints, but guess what we are also so busy and we can't even respond to tickets " also you can't really talkshit about it. but honestly i've been trying since the server went up yesterday and to this very moment i'm typing this im on queue trying to play the game i paid for but i can't..... this is a mess let's all agree that it deserves a negative review on steam until it's fix.
