EDIT: Sorry. This issue is now fixed. All I had to do was update my game. Sorry for being stupid!

Whenever I right-click on 'Market Auctioneer' my game crashes and this message is shown:

"Sorry an error has occured and the game has crashed

Error report has been sent, please close this application"

My bank works fine. Everything else seems to be working okay but I cannot access the auctioneer anymore. It has been over 2 days now since this has happened. Have tried restarting client. Any ideas what's going on? Thanks.
