After successful connection to the server and after disconnecting from it i can't connect to any server (receiving Time Out) as u can see at the screenshot. Could anyone say to me plz what is the problem? Also when firstly connected to the server , the sources connects to me very very slowly .. it's like 8/450 and that number of sources still for a long time ...
Need help ..

Does manually connecting (double clicking a server in the list) or manually disconnecting and reconnecting (clicking the connect/disconnect button twice) help?

About the second part, can you re-check the limit on your tcpip.sys? A recent Windows Update might have changed it back to 10. Set it to at least 50. (if you don't know what I'm talking about, search the forum for tcpip).

The solution for 'second part' helped. Thank you. But i can't still connect to the servers after disconnecting ...
someone told me it becouse of NOD32 that i'm using is it true?
And about the fisrts part .. it's all manually it's not a connection crash ..

Also, please enable debug log in preferences. There may be important clues in the messages there.

Ok, tnx. It seems like it works now .. thanx for the help!
P.S: I should install that patch everytime i install windows?
Will that worning from MS (that this patch replaced original files) appear again?

Yes and yes.

You need to patch the file to increase the limit every time you install Windows, and check periodically so that if a Windows Update has reset the limit back to 10, you can patch it again.

The warning comes whenever a Windows operating system file is modified or replaced. Ignore it only in this particular case - since you have made the modification - but listen to the warning in every other case.
