ok, i just checked on payment history it say's "Check Error - State Unknown", does this mean the check has already been sent out or what? this is for earnings in december. waiting for a reply.
You don`t have to worry about it , the check will be out from their door when you`ll see a check number . I had the same message in my ypn and i did received the check.
This is described in more detail at this thread: http://forums.digitalpoint.com/showthread.php?t=55128
For all noobs: Your check status will still say "Check Error" even days after you've already received your check, cashed it, and spent it on a new 50" HDTV. I and many others have mentioned this annoying little problem to Yahoo and the response has been essentially, "Yes we know."
