Autokicked from singleplayer

I recently started getting a problem where I will be autokicked from singleplayer after opening adv. dupe a few times. (in a short period of time) the number of times seems to corolate with the map too. (some maps it will take more openings of adv. dupe than others) but it will autokick me with the reason:
client 0 overflowed reliable channel

Try reinstalling ADV duplicator

I have adv. dupe updated up to the latest version (SVN) It started this after the last update.
