Very strange problem. Last week I was unable to log into my account, it gave me 5 attempts then timed out for 15 minutes. I was pretty sure I was using the right password. So I followed the link to have it reset and the e-mail didn't arrive. Kept trying this every day but nothing.
Tonight, after several attempts over a couple of hours, I was able to login using the same password as before. Then I logged out and couldn't log in again. Then about 10 minutes later it worked.
Anyone having similar problems?
