I am running SAS 4.26.1000 on XP PRO SP2. defintion DB v core=3855 trace=1807, defintions updated 04/09/2009. The "check for update" button fails, first I see: "checking for updates", then I get this msg: "There was an error trying to retreive defintions....". I made sure zonealarm firewall is not blocking SAS. Also I am able to get to google, etc. I exited SAS, then I downloaded the latest SASDEFINITIONS.EXE and ran it, it said it was for core defs: 3855 04/20/2009 trace defs:1807 04/20/2009 the SASDEFINITIONS.EXE runs OK but when I run SAS again it still says: defintions updated 04/09/2009, why doesn't it say 4/20 or todays date 4/21? And why does "CHECK FOR UPDATES" fail all togehter?
