Cant get on my LDS Account

[patstap]

I keep getting the same message...
Either the MRN and/or Birth date is not valid or the account already exists.

My MRN# is correct and so is my birthday date. Now how do I find out if the account already exists?

You need to recover the account that is associated with your MRN (based on what you've said, there is almost certainly another account associated with your MRN, perhaps one you created some time ago for FamilySearch or some other Church system). To do that, go to the regular LDS.org sign in page, click on the "Forgot Username?" link, then choose the "Membership Record Number (MRN)" option.
