I've been trying to log in for the last hour or so, and every single time (be it with the Steam install, or another install off my hard drive), I get this error "Everquest II has detected an unrecoverable error and must shutdown. <verify> G:\live\eq2\framework\core\devices\Directx9RenderDevice.cpp (2018): failed to create D3D device for NVIDIA GeForce GTX 560 01a380f9
well, after doing a full file check, validating the files, or whatever on the advance tab, and having to reset my screen resolution, I can play again..
Not sure which exact solution ended up working for you, but validating files can often fix a number of problems for players experiencing crashes or other issues like this. In any case, I'm glad things got sorted out!
