Installation total HANG

Hello, guys.
Well, I got the dumbest error I ever encountered in Drupal.

I cannot install Openpublish: it hangs on the first step, when I choose and click "Select language".

It's not max_execution_time problem or this kind thing. At first got
"Fatal error: Maximum execution time of 60 seconds exceeded in C:\wamp\www\openpublish\includes\file.inc on line 937"
but I managed to set the time to unlimited.
I did all this right:
http://groups.drupal.org/node/67393
http://befused.com/drupal/max-execution-time-error

So, now the script has all the time in the world to run (Core2Duo, 3GB), and it just keeps going...

I tried varios older versions of Openpublish - the problem is the same. Tried restatring the server (WAMP, PHP5), other people tried installing on different server - same problem. Tried every solution on the internet, and they don't solve the hang.

Any suggestions about the mystery?

(Check out that line. Maybe the problem and the solution both lay there.)
