Cannot get tiaacreff price updates

[tstalker at word-builder.com]

I haven't been able to get price updates for cref prices from  
tiacreff. The funds are all of the cref funds (CREFbond, CREFstok,  
etc.) I haven't changed anything in the price quotes tool or install.  
It hasn't worked for these price updates since October 6.

Does anyone know what I should do to get this working again?

Thanks,

DJ
