Xenobot license stolen?

[serious]

About 20 minutes ago i got kicked off my xenobot, when i try reopening it and logging in i get the error
Account registered to another machine.
you have 8 days before you can change to this machine.

I dont understand how something like this happened,
my xenobot forum password is unique, and no one could of guessed it.
Im really annoyed by this, and if its my fault someone let me know why
and how to fix it please..
