There can be numerous reasons you have this problem.
1.You created the account with a temporary email address which no longer exists.
2.you might have typed the name wrong or wrong password.
3.Unless someone else besides you has access to the email u used to sign up.. the only way your account could be disabled i think is by a moderator/admin of flyordie.
Unless you did it yourself by mistake & arent aware of this...(i doubt) xD
I would try the following:
Check the email you used to create the account , and make sure you confirmed its registration.
copy The name from the email , and paste into the log in page.
if this does not help then good luck.
