At this point, if you run "dmesg", do you find the following in your 
kernel log?

Digium High-Performance Echo Canceller, version 8.20
Optimized for "i386" CPU architecture
Coypright (C) 2006 Digium, Inc. and Adaptive Digital Technologies, Inc.
This module is supplied under a commercial license granted by Digium, Inc.
Please see the full license text supplied by the accompanying
"register" utility, or ask for a copy from Digium.

If not, you've probably not got Zaptel built with HPEC properly.

Hmm... not run into this myself - after registering my key, it worked 
first pop for me, giving the following output:

# ./zaphpec_enable
Digium High-Performance Echo Canceller Enabler
Copyright (C) 2006, Digium, Inc.
Version 1.0.0
Use the '-l' option to see license information for software
included in this program.

Found key 'HPEC-xxxxxxxxxxxx' for 4 channels.
Found valid HPEC licenses for 4 channels.
Successfully enabled 4 channels.

After this, the follow line is spat out by the kernel:

hpec_license_check: License granted for 4 channels


Cheers,
    Nic.
