    Im not completley sure what is wrong but I have run multiple Minecraft servers. I would download the latest JRE to see if that fixes anything. But if that does not work try Redownloading the server software and server.exe from Minecraft.net Latest JRE: http://www.oracle.com/technetwork/java/javase/downloads/index.html Also be sure that the server.jar and server.exe are within a folder by themselves so files aren't created everywhere. Tip: Minecraft server software is not compatible with bukkit plugins, so if you are making a server and hope to add plugins, download the latest version of craftbukkit.jar and then make a notepad document with this text inside: @ECHO OFF SET BINDIR=%~dp0 CD /D "%BINDIR%" "%ProgramFiles%\Java\jre7\bin\java.exe… -Xincgc -Xmx1G -jar craftbukkit.jar PAUSE save that as server.bat and once you get the craftbukkit.jar into your server folder just rename it to craftbukkit.jar so the batch file can recognize it. Then run your server.bat Craft bukkit download: http://dl.bukkit.org/downloads/craftbukkit/ Hope this all helps!

So the error is caused by it trying to read a file and encountering an issue. Try to make sure you have all the sever files. Make sure the sever is in a drive with enough space and that the folder is not read/write protected. Other then that try googling, I'm sure plenty of other people have had the same issue. Try asking on minecraftfourm.net, they would know better then most people here.
