I'm confident that it's working. The problem could be, in order of relevance:
- Ratboy hasn't gotten around to responding
- Ratboy needs to investigate your inquiry to provide an accurate response
- Ratboy has not seen the PM, even though he's been in the forums
- Ratboy did not get the PM due to some error when it was sent
Give him a few days to get back to you. If after a few days you still haven't gotten a response, send the PM again.
