The issue with ICO this morning has been fixed. This could be a seperate issue. Is there any chance that someone got a hold of your serial number and is currently logged in?
If this is refering to me, I don't believe so. As I said, my issue was due to port 7000 not being open in firewall (FAQ didn't mention this, since it has changed for 1.1 from 6000). I then was playing OK over the weekend, but not last night. I will find out tonight when I get home if I am still having any issues.
Also, the email I got from "Josie" (I think it was to ironclad support - it might have been the stardock auto reply - I emailed the ICO down issue to both) suggested making sure Sins was fully updated via Stardock Central.
And while I am nit picking, The Monk's guide on the FAQ page doesn't link to anything. Small issues, but will help people if they know about it etc...
