ComputerCraft Fails to run.

[cookingboy3]

When beginning my server, everything runs fine, but when using a computer, posts [sTDERR]s into the console, and doesn't start the terminal. It says something like:

ComputerCraft: Error running task.

java.lang.NumberFormatException: null

at java.lang.Integer.parseInt(Unknown Source)

at dan200.computer.core.Computer.getUserDir(Computer.java:636)

at dan200.computer.core.Computer.initFileSystem(Computer.java:662)

at dan200.computer.core.Computer.access$1100(Computer.java:26)

at dan200.computer.core.Computer$1.execute(Computer.java:903)

at dan200.computer.core.ComputerThread$1$1.run(ComputerThread.java:67)

at java.lang.Thread.run(Unknown Source)

then the player sees the computer terminal screen, but it's just black, as if the computer wasn't started.

Try redownloading the ComputerCraft zip, it seems like the pre-installed programs are corrupted or something.
