Hi Erwin,
thank you for your reply.
I configured it through GateKeeper, it starts well first or second time after installation.
You may see actual settings at screenshots:

GDP protokol was disabled from the beginning, later i enabled it becouse i found some info that Gatekeeper probably uses it to connect to wingate service, but it doesn't help.
I used version 4.x.x for a long time, and GDP protokol was disabled there, and Gatekeeper worked well.
I tryed to start Gatekeeper using all possible ways - with doublclick and with right button clickon on icon in system tray, startin' .exe directly, through StartMenu - result is allways the same - it starts and i see it as running process in TaskManager, but no user interface comes.
I may acces and configure wingate from a remote machine, what i exactly do:-). Actually, it is OK to control it from a remote machine. But the fact is, that this problem appears on another machine with similar config, so i would be thankfull for any idea, what is wrong.
