Flexlm troubles

[Zigmund]

Please give me some advice...

What I have...

target protected with flexlm 8.0d (with
apportunity SPROAUTH and HASPAUTH)...
I also have license with SPROAUTH:

FEATURE VULCANMERGEO1 MAPTEK 1.000 permanent uncounted \
VENDOR_STRING=....(long printable) \
HOSTID=SPROAUTH=.................... SUPERSEDE="VULCANMERGEO1 \
VULCANMERGEO2 VULCANMERGEO3 VULCANMERID2 VULCANMERIDIAN \
VULCANMERIDRENT VULCANMERING3" user_info="mergeo1 - Meridian" \
ISSUED=19-mar-2002 SIGN=10AAC4A4D687

What have I done:
1) discovered correct seed1 & seed2
2) discovered vendorkey1..vk5
3) patched makekey.exe (8.0c) with glseed
and seedval (8.0d)

Problem:
When generating network license for VULCANMERGEO1
(or any other represented) I have error:

FLEXlm checkout error: License server does not
support this feature
Feature: VULCANMERGEO1
License path: E:\flexlm\1.lic
FLEXlm error: -18,147

I searched for correct featurenames, but did
not found such... How should I search?
Please give me advice. What should I do?
Or it will be easier to emulate Sentinel key?
If yes then how?

What do you think?
