Flexlm 7.2 LIC file use on Flexlm 9.2 display error -73 ?

thanks
set break in _xorname i get the job & structure, use lmrecode to generated vendor keys and new seeds, build lmcrypt.exe use 9.2 SDK and made a LIC file . but when i use LIC file it still display
Flexlm error -73,125: Local checkout filter rejected request.
even i set the 2 bad flag with 0 and 1--introduse by the FLEXlm latest information "Flex2004.htm" by CrackZ , . but it still display the same error -73,125.
i think this software maybe has another checkout adress for LIc type,
is there anyone met the same problem and how to deal with it?
