I just checked on my MySQL, and the correct syntax is "modify", not "change", for the alter table statement. "Change" is for changing the name, I think.
Also, the size of the int data type isn't necessary, but specifying "primary key" if the field is already the primary key results in a "Multiple primary key defined" error. Just omit the primary key part if it is already defined as the primary key, it will keep that constraint. So the correct syntax should be: alter table Members modify RecordID int unsigned not null auto_increment; Hope that does the trick.
