Hmm... the newest ones on the filebase are these:

I know that I tweaked and fixed SoUlFaThEr's standard map waypoints once, but TBH, I'm not quite sure if they were packed with later bot releases or not. Let's see: Can you tell me the date and file size of your de_inferno.pwf?
The latest one I have is from November, 7, 2004. Its file size is 87.7 kB (89.840 byte). If yours is the same, I'll have a look at the waypoints and try to fix any problem there is. If yours is older, you can try using the newer file first. (In case the version I have isn't available anywhere, I can attach it here).
*EDIT*
Has de_inferno changed between CS 1.5 and CS 1.6? I've been using 1.6 for quite a while now, so I really don't know any more...
