Client freeze problem

[Kirill]

I experienced freeze in main menu several times (yesterday and today). When i click Multiplayer-Yes-Lan/Internet, table opens with no servers present, and everything freezes for 20-30 seconds. Then everything is good until i click choose new server (changing acc). No servers, no freeze, i just need to wait few minutes to see first one, and logging takes around 30 seconds too. Any ideas?
P.S. Internet connection is good, ping varies 25-40.
Tried: rebooting, reinstalling Disco/Original.
And sometimes (like just now) it works fine until i restart freelancer.
