the best is to uninstall and install the latest version...a couple of days back, my Ares didn't connect for 2 days, then i downloaded the latest version and installed it (remember, first uninstall the current one and install the new on then, DO NOT install on the existing one) and then it was working just fine...at this very moment i'm downloading stuff at more than 14 kBps speed and uploading (other users downloading frome me) at around 7 kBps... 😀
