CBQ simply doesn't work

I can't get the CBQ running on 2.2.17. Alexey look like he doesn't reply to his
mails.  I made one more man to check it over me. We both can't find a problem.
The file with config info is attached.

Eager for any idea

Problem: I tested running two links browsers at 62.80.85.74 and 62.80.85.76
downloading both the same big file. They behaved just as without the packet
scheduling. Their behaviour was random and they shared the link statistically
about the same. Then I run donload on the .74 and ssh at .76 and usually I had
to wait about a minute to get a connection which showed also it simply didn't
work. Running these things separately indicated there were no other problems
in the way. The packet scheduling simply didn't work.
