Dear Ultrasurf users:
Due to greatly increased demand in Iran, our servers with limited capacities have been overloaded and start crashing. As a result, you may experience slow response or disconnections, for which we apologize. We are working to deal with the problems and will keep you advised of the situation. In the meantime we thank our users for your patience and support. Making it possible for you to access to the internet and to bypass internet firewalls during hard times is why we have created Ultrasurf and why we are working so hard to expand, improve and protect its service.
But as for me It simply works now, at moment.
Anyway check if you do have latest Ultrasurf. Try to update your Ultrasurf for K-meleon with
newest version (just unpack archive in KM working root folder - and agree to overwrite existing files).
It requires UltraSurf to be unloaded, but you don't need to restart K-Meleon!
