Negative request count comes from opening a premium account and at the end of the month you cancel your account after requesting the maximum allowed. Since requests are given back on a weekly basis (7 days after you made the request); You will have to way until that 7 days passes before this will go current again.
Unlimited accounts are different however; if your premium account expires you will return to 4/4 requests remaining. It would be absurd to leave you with a -1,000,000/4 remaining. lol.
If you see this error message, negative request count may be the reason!
