Problems with custom UI since mar 3 update

[BullMarkOne]

well, just tried to log for first time since the patch this am and what do I find? nothing but a black screen.. then a few seconds later I'm looking at my desktop, and an error reporting popup,yay

well I'd added a couple things to my custom ui folder so I tried taking them out and starting again, but same problem. Third time I tried renaming my eq2.ini and starting, got into the game just fine this way.

The black screen is popping up just after I hit the 'play' button, and crashing occurs without any changes on screen.
