nmap 5.35DC1 for windows can't scan

[Alexander Khodyrev <spxnezzar () gmail com>]

Hi all.
I downloaded the other day nmap 5.35D1 for windows and ran to the fact that
this version can not scan anything except localhost. When trying to scan a
network (like 192.168.0.0/24) nmap reported that all the hosts down. In 5.21
there is no such troubles. where to look? or i need to take svn for windows?
looks like that:

C:\Documents and Settings\SpxnezzaR>nmap 192.168.1.1
Starting Nmap 5.21 ( http://nmap.org ) at 2010-12-08 19:45
Nmap scan report for private-address (192.168.1.1)
Host is up (0.015s latency).
Not shown: 996 closed ports
PORT     STATE    SERVICE
21/tcp   open     ftp
23/tcp   open     telnet
80/tcp   open     http
8080/tcp filtered http-proxy
MAC Address: 00:13:49:77:04:84 (ZyXEL Communications)
Nmap done: 1 IP address (1 host up) scanned in 2.73 seconds

and 5.35DC1:

C:\Documents and Settings\SpxnezzaR>nmap 192.168.1.1
Starting Nmap 5.35DC1 ( http://nmap.org ) at 2010-12-08 19:47
Note: Host seems down. If it is really up, but blocking our ping probes, try
-Pn
Nmap done: 1 IP address (0 hosts up) scanned in 0.61 seconds


192.168.1.1 - it is home my ADSL-modem
