Whew..    3 days of support tickets and emails later.  I was finally able to at least get copy of the server files.
I would recommend people stay away from lethaldrive servers, except they just went under so no reason to stay away from them anymore..   Heh..
Anywho. I spent all morning getting this done.  I zipped together the world dat files from the server and uploaded them so anyone can download them.   I had to make a free account with Mediafire to do so, so there is no guarantee how long the download link will last.  So might want to get it as soon as you can.
I was able to use the files to get a local copy version of the server. (At least the normal world) Up and running within a few minutes.  They seem a bit disorganized with how a vanilla server stores it's files.  But moving them around a bit I was able to get them to work and the world looked like it was all there.
Really didn't have too much more time work on it, I gotta eat something and get to work. I just feel a bit better this morning knowing that at least the server files were recovered, so technically if someone feels up to it, it can live on.  I suppose if nothing else everyone can download a copy and have a copy of the work everyone put in too.
Again I apologize for any problems this has caused everyone.  It certainly was not my intentions.  
Here is the download link for the server backup files.
