Can't get through the command prompt

[Sebby]

So I heard about this game, registered, downloaded, and started to install. After installation, I tried to run LM and the update.exe, it won't let me get in the game. I had checked firewall and anti-virus, everything was fine. I have tried running as administrator, no help.

All this game gives me, is the following (taken from the update.txt file):

Traceback (most recent call last):
  File "<string>", line 77, in <module>
  File "C:\Last Moon update\build\pyi.win32\Last Moon\out00-PYZ.pyz\urllib2", line 126, in urlopen
  File "C:\Last Moon update\build\pyi.win32\Last Moon\out00-PYZ.pyz\urllib2", line 406, in open
  File "C:\Last Moon update\build\pyi.win32\Last Moon\out00-PYZ.pyz\urllib2", line 519, in http_response

  File "C:\Last Moon update\build\pyi.win32\Last Moon\out00-PYZ.pyz\urllib2", line 527, in http_error_default
HTTPError: HTTP Error 403: Forbidden

Anyone could help me with solving my problem?

Firewall or anti-virus is blocking it, can't say more than that since we don't know what software you have installed

I got LM from here (obviously) using the main link, and am using F-Secure anti-virus.

then disable f-secure and see what that does

then disable f-secure and see what that does

Disabled F-Secure to try update.exe or Last Moon.exe, no difference, still the same message.

then you have something else that's blocking it
