Installation problem(hldsuploader)

[[][shadow][]]

I downloaded hldsuploader.
And in this step:

Now click on Start, Run and type cmd . Type in the commands mentioned here and end a line with the enter key.
Command(s):C:
cd \srcds
hldsupdatetool

First time I did this it work,but this time,it didn't
It says:


I don't have any other programs on..

What should I do?

Maybe because steam is running at the same time?

I tried both steam on and off.
Only steam.exe and hl2.exe is on(I guess)

Reinstall it?
