Black Screen when loading into Sunken Temple

So I still have to do the Sunken Temple(Hard) and the Wander's Palace(Hard) in order to do the Roulette's. But when the Sunken Temple pops on DF and I accept it I get a black screen during the loading process and it never goes away. I end up having to close the game and re-open it again after about 5min. Someone in my group the first time this happened said there had been issues with different servers not connecting, so I assumed it was a known issue and would be fixed during the maintenance but no such luck. So just wanted to bring to people's attention.
