My SAS software says that my license has expired.
SAS licenses are leased on a fiscal year basis. You should receive a SAS Installation Data (SID) license file (versions earlier than v9 it is called a "Setinit") when you purchase SAS. This license allows you to use the software from September 1 through August 31.
Typically, SDS will not receive updated SID files until late October or early November. Although the previous year's files will have expired, they have a built-in grace period of 90 days that will allow you to continue using the software.
