Error Code C10 on Nar Shaddaa

Hello,

So I've been having a strange bug (probably due to the new event). Where I straightup cannot enter Nar Shaddaa anymore. I've tried it with two characters, both Jedi Knights, and neither has the quest from Tatooine.  Either way, when I try to enter Nar Shaddaa through exiting my ship or the galaxy map it gets stuck on the loading screen.

Giving the message "Error C10, client failed to deserialize a binary header file. Exiting game" after which the game closes down. 

I thought it was a general error after some memory leak, but it's hyper specific to Nar Shaddaa for now. As I tested and entered Coruscant with absolutely no trouble, and was doing quests on Taris earlier as well. 

If anyone knows if there's any way to fix it? Thank you
