Unable to add a new member in Member Management

The club number is 5005.
I tried adding a new member to membership management, but I was unable to do so due to the error shown below. 
Help, please?

5005 is not a valid FTH club number

Sorry, Brian. I made a mistake with the club number.
The club number is 5002 OMNI Toastmasters club in Brooklyn NY.

Should be ok to add now.
