Unable to find the maintenance token for TeamCity in the server log -

i installed teamcity on windows server 2012. has been working fine setting few builds. attempted install plugins putting .zip files in ~/.buildserver/plugins folder. restarted server cd'ing c:\teamcity\bin , running "runall stop" followed "runall start".

then when go teamcity page several minutes "enter maintenance authentication token" page. says on page find maintenance token in teamcity-server.log file (see screenshot below). in c:\teamcity\logs\teamcity-server.log , has several "super user token" , "agent authorizationtoken". tried using these token invalid maintenance token error.
