   Hacking advice needed

   Hello folks,   
      
   I'm having a bad time trying to crack a flexlm-based protection.   
   Sorry if this is not the right place to discuss this.   
   I'm trying to get past the protection of a software, you know, for evaluating   
   the full version before buying etc... :)   
      
   I'm not new to hacking having done some work on 8-bit systems in the good old   
   days and on more modern systems as well. I cracked some flexlm-based schemes   
   but it was very easy because those were using the lmgrxxx.dll so that the APIs   
   had very informative names on them...   
      
   Now I'm having two main difficulties:   
   1) The flexlm protection is not dll based but has been compiled into the   
   application, so that there is no way of finding out the usual APIs   
   (lm_checkout etc...)   
   2) The program runs in a multithreaded fashion so that I'm getting lost with   
   too many threads trying to understand which thread actually performs the   
   license verification.   
      
   I'm using Win32Dasm 8.93 and IDA 4.8.0, I perfectly understand assembly   
   language but I'm not so familiar with Windows APIs.   
      
   Any advice on how to proceed is highly appreciated...
