Hi, i'm newbie here......... and i'm a new xunlei user....

i'm using the latest xunlei for 2 weeks and the speed is good. However, sometimes it hang and the speed drop to 0kb/s. i have to close xunlei and restart it then only back to normal. sometimes, i even have to restart my pc....

i'm thinking of downgrade it to older version. do i need to uninstall the current version first before install the old version or i just install straight away on top of the existing version?
