What password did you enter when you was installing the template?

I installed 10 times,
with no password
with admin
with 1234
etc

not work at all

Sorry, but I really can't help you with local installation. If you can try to install in on a web space, we will take a look (if you still have problems).

I made PHP upgrade to 5.2.9 and the administrator area works fine now.

Thanks.
