Credits

Hey, :]
 
I went to visit my forum today after the updates and noticed I had -17 credits, when I haven't done anything that has anything to do with credits!
 
Two questions...
1. Why is this? Could it be something to do with the updates?
2. How could I change it back? Or is it ok to leave it?
 
Thanks for your help!

It's ok. We are doing some updates at the moment

Phew, it's gone down againto -20 and I was panicking there for a moment! xD I thought someone had maybe got onto my account and was I thinking of changing my password!
