Playing dungeon defenders on PC, i was in my tavern and moused over the challenge Lab Assault I hit the get button and purchased the necessary DLC to unlock aforementioned DLC. However, upon returning to the game it continues to not allow me to play Lab Assault and simply has the 'Get' button up where the 'Go' button should now be. Exiting the game and restarting has provided no avail and I am also unable to even repurchase the DLC. On steam it shows that my DLC has been purchased and downloaded as well. I bought the DLC approximately 2 days ago.
Thanks in advance.
