hmm first time today i saw some "EUE" errors (early unit end) which result in a UNSTABLE_MACHINE error in the log then the client just says "pausing for 24 hrs"...
seraching online its some issue with the cuda driver which apparently gets messed up if you run other graphics intensive stuff... a quick fix is to restart FAH client and/or reboot - restarting client got mine to run again.
I'm not being able to fold regularly as my El Nova 1KV UPS quits on me if there's a power cut and my 280 is working at 100%. Waiting for a APC Smart UPS before I can contribute to the team regularly...
Not directly related, but pappu, are you using the console or graphical GPU Client? I'd recommend the console version as it folds faster.
Anyway, regarding the download problem, this can be due to your internet bandwidth being used fully by something else (P2P ?) or it could be that you haven't chosen the "large packets" option in the configuration (which is not enabled by default) and so the server doesn't have any work units to assign to your client?
