[SOLVED] OTM 6.3 - unable login after fresh installation

Hi everyone!
I have installed OTM 6.3, and I have change OHS port to 80.
After startup, I can see login page, but if I press "Login", nothing happen.
access_log:
* - - [10/Apr/2013:13:10:22 +0400] "POST /GC3/glog.webserver.servlet.umt.Login HTTP/1.1" 302 215

This all, that I find in logs.
