I purchased a new laptop, and copied over my EQ installation. I have tried multiple directories to store it in but I'm having a strange problem. IF I delete EQclient.ini, after server select, it loads fine. As soon as I log out, now EQCLIENT.INI is saved, if I try to relaunch EQ, I go to a black screen after server select and never get in. I've tried deleting specific portions of EQCLIENT.INI (resolution, etc) but no, the mere presence of the file seems to prevent EQ from loading. If I delete EQCLIENT.INI, I can get in, (having lost all my button configs) and use my UI, etc etc. No worries. But SOMETHING doesnt like Eqclient.ini being there.
Try the following: Right Mouse button Click the EQ Icon, select Properties then compatibility then put a check in the box for "disable full screen optimizations" hit apply then run as administrator the first time you log in
