Hello Ana,
 There could me multiple reasons for the same. Try shortlisting the same
from here for a start.
* Is your kernel patched with htb support
* Upgraded to 2.4.20> preferably 2.4.21 which has wonderful support for
HTB inbuilt.
* Does your version of tc support the same.
* If not google for htb and get the tc binary from their homepage.
