That network is mostly well-known for it's file sharing channels. Therefore, if you're mass file trading (particularly big files on a slow connection) that could well be the source of the issue. If you think this is the issue, stop file sharing smile

If it's not that, and you're using Criten to chat, then perhaps it's an issue with the server you're on and not your end. Perhaps the server is being attacked. Try using several different servers. Alternatively, contact the network administration and see if they can offer further advice as to why it may be only Criten causing you this issue.

Best of luck.
