Rhaervis, I'm having the same errors as OP. I'm however running a Mac version of the client. I know it's basically the windows version in a Wine64 loader, but I've been getting these errors constantly. Sometimes I can play for an hour or two without the error, but other times it will error within a few minutes of loading the game. I've been following this thread for a few days, but waited to comment as I was hoping the patch 5.5 hot fix that was performed last night might help with the issue. Unfortunately it has not. I have tried a number of steps, such as making sure I have no other apps open and running while playing, and even deleting and reinstalling the game. I reinstalled after trying a few suggested fixes from the forum such as removing the config file and starting a fresh one, even removing the wine64-preloader file from the package contents as suggested by some other Mac users. I tried to get the system information as suggested by Dynratygus earlier in the thread, but my menu appears to be different in the launcher. I've been playing several months without any issues, then patch 5.5 was released, which I downloaded and installed, then I had the battery in my laptop replaced and the errors started. That's when I started with the various troubleshooting steps, and reinstalled the game. Any other steps or suggestions would be greatly appreciated as I am at the point of cancelling my subscription and deleting the game.
