Can´t LOGIN - need HELP !

i wanted to install the statistics, but the install-function didn´t work. So i tried to install by my self. After a long time of hard work, i got the page on the Screen for login:
i changed in Mysql the STAT_USER and the STAT_PASSWORD.
But it doesn´t work.
I also think, that there is no INDEX created in the Database. I didn´t find out on what field the index should be.
Can you help me to go on....

Hallo, i have seen now, that there are "statistics" from the webpage for the Database in field stat_stats
There is no entry in stat_stats_clicks.

So, may be, this could help.
