CD key in use by me

Hi been playing diablo since d1 :slight_smile: so for about a week I have been running 2 profiles and last night my second key says it’s in use by me (my install key) this all happened while I was asleep. Anyways I have redone everything except reinstall diablo. It’s like the key swaper isn’t working any ideas? Weird this just happened all the sudden

So it looks like it’s working now I read somewhere to give it a day or two. So what was it that went down b.net put a lock on my ip or something?
