The logs don't seem to work although it may be a file conversion issue as I'm trying to read them on the mac. It's not like I know anything about coding anyway but they tend to be legible enough for non-coders anyway that they supply enough info for a thorough google search and troubleshoot.
I've done some digging out of just what you have told me and there may be some possible issues:
Id limit reached: Highly unlikely as you only have LOTR installed. Would be some weird issue fixed by reinstalling the mod/extracting it to a jar file instead of keeping it as a zip if this was the case and making sure your using forge 1.7.10 - 10.13.4.1558
Since you seem to be stuck in space it may be the server freaking out with the spawning changes in the LOTR mod. Maybe started in the default demension and travelling to middle earth might fix this. Another way would be to open the LOTR.cfg file in minecraft/config with two lines in interest to play around with:
If enabled, when a player dies in Middle-earth far from their spawn point, they will respawn somewhere near their death point instead B:"Middle-earth Respawning: Enable"=true
Threshold distance from spawn for applying Middle-earth respawning when the player's spawn point is the world spawn (no bed) I:"Middle-earth Respawning: World Threshold"=2000
Playing around with these two lines by changing true to false or the respawn threshold might fix it. (might) (Maybe change spawn radius to 0)
Installing the 'perfect spawn' mod might help as well.
