Do you mean LCR (Leader and Clerk Resources)?
https://lcr.churchofjesuschrist.org
How are you attempting to access it? What kind of computer/device? What browser (if any)?
Does your Church Account have your Membership Record Number tied to it? If you can see the ward directory and calendar, that's pretty good evidence that your MRN is on the account.
What happens when you try to access LCR? (Please be as precise as possible, screenshots if necessary.)
