Unrecoverable error

[RdHtEMT]

I installed EQ2MAP and the framework. When I hit play on eq2, I get this error message.

Everquest II has detected an unrecoverable error and must shut down.
<verify> C:\live\eq2\framework\core\devices\src\DirectX9RenderDevice.cpp (956)irect X error.(D3DERR_NOTAVAILABLE)
I get it even when just clicking on EQ2, not going through the EQ2MAP shortcut. I'd appreciate any help I can get, since now I can't play EQ2, and could before installing EQ2MAP.
Thanks.
