The software developer of TradeBullet, a C2 compatible software program, has asked me to inform all C2 users of the following.  
  
All users should update TB to build 876 or later which supports a mandatory change in license validation. Previous builds are not guaranteed to work. Simply install the new build on top of your existing one. Your settings will be preserved.
