What happened to my user-defined server-side trace?

Hi Everybody,

I created a server-side trace that automatically stopped itself Sunday at 7:00 a.m.  That was TraceID = 2.  Now, Monday, when I execute "SELECT * FROM fn_trace_getfilterinfo(2)", I see that TraceID 2 no longer exists.  Is there some way to restart a stopped trace, or does the server lose all memory of the user-defined server-side trace once it's been stopped?

Thanks,
Eric
