hey if this keeps happening to you later and after a reboot, try shutting down your firewall and anti virus. If it still doesn't work try plugging directly into your dsl modem after renewing the ip address you should be ok. If not then it's routing issues on their or your isp's end. However, I would look at your computer first to ensure it's not you and you alone...you app may be fubard,...
or your patcher may be fubard too.
So to review:
-Try a reboot
then
-Shut down firewall/antivirus
then
-bypass router
then
-try long patch method or reinstall aces high as patcher may be fubard
then
-talk to isp or hitech support.
Let me know what finally resolves the issue.
