Flexlm ECC

I am trying to reverse a flexlm protected program which uses ECC.
I Managed to find the seeds and features, build lmcrypt, and patched l_pubkey_verifyl
However the program refuses to run, and crashes every time, so I assume that it uses some form of CRC check, and crashes because this value has changed due to patching.
What is the general approach to defeat the CRC check?
