Needs help with Graal3d levels

[ArmadeusWarlock]

For anyone that knows how, I need help on converting my .rmf files into Graal3d levels. If they need to be a different extension, please tell me. Or do I need to use a different extension? I've been using Worldcraft, as someone told me to do. Tell me if im doing this all wrong or if I need a special program to convert/make the files.

And since I am sure I will get about 99999999999 messages on where to get Graal3d, here is a url:

And also, I cannot get beta 3 to work, it says I have a glide2x.dll error.
Please help me on any of these problems I have!
Thx!
