Which version of SAS are you using?
If you aren't sure you can try running this code:
Proc Setinit;
run;
The Log will then have some of the SAS license related items. Likely the second line of output will look something like this:
Current version: 9.04.01M4P110916
Share that with us.
That message could mean that the place you are getting your data from has changed. Depending which version of SAS you have and the other files different options may be needed.
