Unable to update

[RATICIDE]

Hi,

I have followed the guide (except creating a steam account as it is written in readme file that it is not required anymore) and then I typed in the following command :

HldsUpdateTool.exe -command update -game hl2mp -dir .

And I got the following error message :
Checking bootstrapper version ...
Getting version 14 of Steam HLDS Update Tool
Downloading. . . . . . . . . .
Unable to update: renamed HldsUpdateTool.exe but the file is still there

Anyone got this error message already ?

Thx for your help guys.
