I have resolved my issue!
Simply, i have downloaded the new version software of Qlik Sense Server (March 2015--> (Qlik Sense v188.8.131.52), and i have re-instalated.
I dont understand why there isn't a clear support or documentation, for something so simple. I have been fighting to resolve several days, and it was as simple as reinstalling a new software again, becuase SENSE is very recent,...and in the part of server, there are lots of problems.
I hope my solution is worth to you!
