I am unable to update the virus definitions on my fresh (yesterday's) installation of latest ESS v3.0.672 64-bit, running on XP x64 SP2 with all updates. ESS seems to connect successfully to the only server listed after installation (u24) but simply reports that I already have the latest updates. I have a retail (CD) version of ESS, but the activation procedure prompted me to download and install the latest version from the web. I have read all the troubleshooting tips in the the relevant knowledge base article and have consulted all the ESS forums. I am an experienced windows user and familiar with firewall function, administration and operation. However, I don't run currently any additional firewalls or protection software (except TeaTimer from Spybot Search and Destroy). I have a direct connection to the internet, no proxies, and a static IP. Are there any known issues, especially for the x64 version, not described in the KB article? Perhaps some registry setting that I could edit to persuade ESS that my virus definitions are old? Or some other procedures (say, deleting existing definitions and somehow forcing an update) I might try? The final thoughts I have is whether the update servers actually need several days to receive my activation information (or having a glitch again). Or whether my logon information was somehow blacklisted right out of the box (literally) due to conflict with existing pirated serial numbers. Any ideas will be greatly appreciated, thanks in advance!
