You need to tell us more about your problem - see the Statalist FAQ,
item 3.3:
http://www.stata.com/support/faqs/res/statalist.html#stata
Which versions of Stata and -spatreg- you are using would be a good
start. For example, my version of -spatreg- dates from 2001, before
Mata existed, so it's hard to imagine how I could get the same Mata
error as you do. In fact, -findit spatreg- doesn't show any more recent
versions, so the version information in your case should tell us a lot.
